my boyfriend and father of my unborn child has always been the type of person to be distant and seems like he always has a wall guarding his emotions. hes cheated on me multiple times and when i tell him im leaving he clings to me for three days then goes back to being distant. all our arguments end the same way, him saying hes never had anyone there for him. is his parents being absent the reason why he cheats and is distant, also how do i make him feel secure and show him that im here for him?
