Relationships

(TMI) Ok ladies, I need some help. I have been with my boyfriend for 7 years now. We first started dating our sophomore year of high school. Now we have a one year old baby girl. Well Wednesday night we got into a fight. He seemed stressed since he got off work that day. Pretty normal. He had a couple beers and was feeling pretty tipsy. Well eventually I was tired and wanted to go to bed. He followed to bed but he wanted to fool around. I told him before he even tried anything that I just wasn’t in the mood but he tried anyway. I tried to get into it but it just wasn’t happening. (I have always had a pretty low sex drive) so he got mad and just stopped and then kind of lost it. He freaked out and was trying to pack his clothes for work and drive somewhere. I told him he was stupid for trying to drink and drive and he just say he didn’t care and went about his fit. He went to walk out and I followed because i needed to lock the door if it was just going to be our baby and myself at the house that night. He thought I was following to stop him and said “just stop” so I told him I didn’t care if he was leaving I just needed to lock the door behind him. So then he grabs a ring box out of his bag and throws it down towards my feet and says “just give it to whoever you’re f*cking, or just sell it” and storms out the door.

I was pretty much in shock that he just ruined something so special. I didn’t open it to see the ring I put the top back on and I set in on the counter and locked the door. Well that was Wednesday night and today is Monday night and we have hardly spoken. He’s been sleeping in our daughters room every night. (She sleeps in bed with me anyway) but I talked to my dad thirsday night about how my bf is convinces I’m cheating(as if I had time, I’m a stay at home mom) and my dad said usually when someone is so worried about the other cheating it’s because they have something to feel guilty about. So now I’m stuck wondering if he is cheating or has cheated and if this is his way of getting out of our relationshi. I don’t even know what to say to him at this point. I want to be happy and I would love for that to be with him but now I’m really hurt that he straight up ruined a proposal. Like now I know he was going to but he threw the damn ring at me. What do I do? Please help!
