I haven't seen enough of Lisa to comment on her as a person but from what I have seen it looks more like a hostage situation then a relationship. Plus I know the way he used to speak about and treat women. He would always try to dominate them either with physical or emotional fear.
Those photos that were shared of the rave looked so set up and awkward again. He is holding the can of sprite quite prominently in the photos to as if say "look I am drinking non alcoholic drinks" (while Lisa is holding his beer).
I am interested in seeing his friend circle as he didn't seem to have any friends when I knew him and the comments I have seen on Reddit showed that it looked like he was hated by people he went to school with. This shows that he is not a nice person if so many people form that opinion on him, no smoke without fire.
