Meeting with my ex what do i do?

So me and my ex boyfriend were together for three years on and off. We split nearly two weeks a go and a lot has happened since then. He'd spoken to his mum and dad about us and they said that he shouldn't be in a relationship at the minute. He's going in the Army. Then last Friday night I had a text message from him saying he weren't drunk and that he loved me so much and stuff so I rang him and he sent me another text after saying he couldn't let go of us... So he came to my house Saturday night and he was a little drunk but he started crying saying he loved me and he didn't care what anyone else thought and asked me to go to his house to speak to his mum and dad so I did. We got woken up by his mum screaming telling us to get out baring in mind he's 21 saying we were using the house as a brothel which we weren't we were going to talk to them...So he walked out crying saying he was going to kill himself and stuff. Since then he's just said things wouldn't work if he went in the Army. I had a good relationship with his mum and dad but now I feel like they hate me and I'm all of a sudden being pushed out of his life. I want to be with him but I don't know what to say/do to reassure him or get him to tell his mum how he feels. He says he'd be paranoid while he was away but i've never done anything for him to be.. I don't get why he doesn't just try and see what it's like? He doesn't go in till January an that's if he gets picked to go in then... I was with him before he decided to go in there and I don't have a problem with it I want him to...
