Search Results: will he change his mind

So my ex and I haven't been split up long but it has been a roller coaster of emotions since the split. One minute he is having sex with me and cuddling up to me at night; the next he is sleeping on the couch. He only sleeps on the couch the night after he spent cuddled up to me. Every time. Never fails. I catch him staring at me all the time and start to say something before he changes his mind and retracts his first words. Whenever we have a really good conversation and giggling like idiots (we are trying to be friends), he will just get this sad, lost look on his face and say that he needs air and will go outside and sit in his car for awhile playing his guitar. Last night he told me that he thought the reason we didn't work out was because two broken individuals shouldn't be together because there is no balance. Just an overload of emotions. He said he wants to be the guy who spends forever beside me but he can't. He also told me, in a drunken state, that he is in a lot of pain and that he often questions whether or not he has made the right decision leaving me and says he will more than likely regret it when he stumbles across my profile later in life and sees that I am married and happy without him. We still live together and the way he talks gives off the impression that he doesn't plan to leave anytime soon. Which I dont mind. I dont usually have a passcode on my phone but my 7 year old kept running off with my phone to watch youtube videos so I put a lock on my phone. A half hour later my ex came out of our room and grabbed my phone to make a call, realized there was a passcode and he got this really weird look on his face. When he handed me my phone so I could unlock it, his hand was trembling. He didn't say anything to me about it but walked out to his car for awhile; came back in, initated sex and then cuddled me on the couch for a solid 3 hours. Which is huge because he hasn't touched me aside from when we are sleeping for the past 3 months. Any ideas?
