Hi there,
I wouldn’t say he is rebellious no. He is the type of person that will try and work things out as much and as long as he can but once enough is enough he is gone. You say he does not want a conventional relationship yet before he left we were planning our future, buying a house, starting a family ect. He’s been quite nasty since our breakup and u can’t help but think that this is because he’s finally starting to feel guilty for what he has done and doesn’t know how else to handle it
