Notice how guys with a history of treating women badly who end up WAY punching with their new partner, are often very happy to modify their behaviour and change their ways because they know they won't do better. Just something I've observed personally.
I think that’s a misconception though, and I think that’s definitely what it looks like from the outside.
I had an abusive ex and everyone told him he was “punching” with me. Our mutual friends and my friends, thought he was the sweetest guy who was besotted with me. But mainly they thought that because he was highly manipulative and very good at coming across as the good guy. He could be very emotional and I think in an age when men aren’t comfortable crying or showing emotions, this made him seem sweet and sensitive, but really he just weaponised his crying against me. Similar to julius, who has this sweet, tortured, sensitive musician front down to a T.
my ex had treated his ex girlfriend before me, not especially well. (I didn’t realise all of this at first) He basically felt she wasn’t good enough and spoke disparagingly of her, took her for granted etc. I wrongly assumed that because he told me he was punching, that he valued me enough not to mistreat me. Had I been older and wiser I’d have seen the glaring red flags and how
deeply flawed my mindset was.
in reality it looked like he was treating me well and that he’d “changed”, and he convinced me that he was. He spoke highly of me to others too, told everyone he’d “never felt this way” before a la Spring Onion right now.
Except, he treated me just as badly, it was just in a different way with different tactics and different mind games. The disrespect was always there for both us women. While he manipulated his ex by going hot and cold, telling her he cared then acting differently, humiliating her and then apologising, breaking it off with her on/off and seeing other girls etc.
with me it was constant guilt tripping, it was huffing and emotional blackmail to get me to play the part he wanted. He’d do seemingly sweet gestures for me for the benefit of everyone else without really caring about if it was actually something I wanted. He’d lie to me too, just about different things. He’d put his own wants and needs first constantly, then make me feel bad if I voiced my own. It was abusive for both women he was with, and his treatment of us was no reflection on us but
entirely a reflection on his own lack of character. And none of this was apparent or obvious to anyone looking in. To this day, most of my friends think he was a sweet guy who just overreacted when we broke up because he was heartbroken. They’ve never truly understood that that was the real him coming out because there was no point in him pretending anymore. Before they groom their victims, abusers groom their character witnesses and people looking on.
so nasty vile men
don’t reform and suddenly treat the new, prettier girl better or value her more. They almost always disrespect and manipulate her, just in a different way. A pretty face and hit body will
never make a man value a woman if he just doesn’t respect women. Finding the “right woman” will never make a man suddenly learn to respect women. At best, he values the physical attributes as a commodity. Eg my ex hated posing for photos with his ex girlfriend because she wasn’t pretty enough for him, but was more than happy to plaster pics of us everywhere. It wasn’t because I was more valuable to him, or he respected me more. It wasn’t even that I was prettier than his ex. It was because he felt how I looked, was a good reflection on him. It was
all about him, always.
so nope, I don’t believe they ever truly amend their ways, unless on the rare occasion they have an epiphany within themselves that has nothing to do with the woman they are with. If Julius treats this new woman better (and I doubt he will) it’ll only ever be because he himself realised how awful he’d been, and had a true change of character. And that doesn’t happen often IME.
In my experience the trajectory usually goes that the guy in question is with the girl and she’s way out of his league. Initially he treats her like a Princess, completely love bombs her. When she’s invested, he’ll change tact, all while appearing to others looking on, that he is a model boyfriend. He’ll start to put her down subtly and she won’t clock into what’s happening because it’s so subtle, he’ll maybe start manipulate her or start slowly with silent treatments. He’ll slowly push those boundaries ever so slightly. Won’t pop out to get a pint of milk for him? Little bit of silent treatment. He’ll be upset but won’t actually talk about why. He’ll call her silly, or accuse her of starting a fight if she points out he’s huffing. He’ll purposefully not text her back when he’s out, allow her to worry then stroll home and act like she’s been completely unreasonable, so that next time he disappears all night he’s laid the groundwork - she can’t complain or she’ll look like a nagging wife. He’ll start grinding her down by small actions regularly, whether he’s subconsciously doing it or not who knows? It’ll get to a point where her self esteem has eroded, her grasp on what is acceptable treatment has been gaslit out of her. She’ll be in turmoil because she thinks she loves this man without realising she’s in love with a front he puts on to manipulate her.
She won’t feel able to leave the relationship (but probably won’t be able to pinpoint why), and that’s when he’ll ramp up the disrespect towards her. When he’ll get a kick out of how superior he is, because he’s been able to beat this beautiful woman so much more attractive and better than him - into submission. Or maybe he’ll marry her and have kids with her in this broken down form, because he knows she’s a safe bet and she fulfills his shallow need for a trophy partner, which he ultimately takes as a compliment to him.
so I’ll say it again,
men who mistreat women never, ever change for a woman. They just change tactics.
Read every single word in her voice, it did make me laugh on the show when she said it and the fact the producers had to find a way to slip in Miles' star sign 
awks. 
Also, I'm surprised he's on Tinder vs. the elitist likes of Raya. Maybe he's exhausted the latter
-theres just something about him that gives me that impression
