Not really. He made it known to the experts before he was paired with someone how hard it is to trust someone and then he gets paired with someone who doesn't think of the consequences of kissing someone else. He might even know that April is fame hungry from appearing on a TV show previously. He's got four kids so bound to be super careful about who he's paired with as at this stage that we watch he's only known her probably two months. I think it shows how good he is at relationships that all his four kids are with the same woman. I am sure the things his exes were saying were looked in to by MAFS producers and if it was anything more than jealous exes trying to bring him down jealous he's getting TV fame, they would have removed him from the show to protect the brand.
How good he is at relationships or how good he is at manipulating people? Just because a woman has 4 kids with a man doesn’t mean the man is good at relationships. He is a walking, talking, gaslighting, emotionally manipulative red flag.
