<human>: Provide a brief overview of the text.

Thanks for looking. About three months ago I started dating my SO and it's been one of the most rewarding relationships I've ever had. I was always a little paranoid because he started dating me very shortly after ending his relationship with his ex of 4 or so years, and I've been trying since the beginning to make him feel comfortable about taking things slow and getting the time he needs to process things.

A few weeks ago our relationship took a turn when I discovered some vaguely romantic exchanges between them and confronted him about it I took the opportunity to make it understood that if he has lingering feelings or things to process, it's okay- but I don't want it to affect our relationship; he ultimately decided I was worth fighting for and regaining my trust.

Our entire relationship we haven't really had sex (he attributes it to stress, I believe learning intimacy with a new person is a slow process) but other than that the relationship has been great. Last week, a mutual friend drunkenly told him in a very rude way that he wanted to sleep with his ex, and since then, it's been a point of stress between the two of us- so now we're having problems being emotionally intimate as well as no sex life. He's been very distant since last week which is totally unlike him, so I decided to give him space to think.

My question is: how much space should I give him? He doesn't want to stop talking, but a part of me thinks I should just back away completely so he can decide what's important.
