Confused about the "Freinds with Benefits"

It was wrong of him to be snappy like that in my opinion. He shunned you in bed, then assumed you would just simply pretend nothing happened and come watch the game? I would say, from this description, that he's a manipulator and gets off on controlling people. If you spend any more time with him, make sure to note how often he does these things. It may be safer to call it off if that behavior continues.

Good Luck.

I'm in kind of the same situation:
New Years Eve I went out with friends and invited my best friend who just moved back into town with his own apartment. Since we drove out of town to celebrate I crashed at his place that night and we stayed up catching up. The next day I went to work and he brought my cell phone because I had left it and asked did I want to watch movies. I said yes and we ended up falling asleep to one of the Matrix movies. The next day I went to work again and he text me and asked what I was doing 2mrw because he wanted to hang out on my off day. It continued this way for 3weeks, progressing into something more than friendship, until I asked to use his phone & another girls' text msg popped up asking if she could come over. I was immediately jealous and grabbed everything I had and left. He didn't call or text me the next day, even though we had been communicating everyday and sharing a bed every night, until my birthday. It was 6days ago, and since he sent the initial msg I asked how come he didn't communicate and did he not want to be my friend?. He said that he thought since I left him in the middle of the night and didn't call or text him why that I didn't want him apart of my celebration. I told him that wasn't true and what happened the text msg and asked had I not been there would he have told the other girl yes. He said that he wouldn't have because I'm the one he wants around him and that he's only happy when he's with me. Yet he didn't say he cared/liked/wanted to be with me. Just that I make him happy and he wants me around. Later on he told me that it hurt him finding me gone like that because others have left him before. I asked why and he said he didn't know how to be faithful. I asked has he learned and he said he is trying. I love him cause we've known each other for 2years but at the same time I'm hurting myself by staying. I tried to leave twice now but I love him and can't see being with out him, although I will if I have to, and every time he begs me not to. He even prayed for help for himself to be faithful and treat me right and my friends say that he seems like he's genuinely trying and that he's puppy dog sick in love over me. I don't see that because all I see is him text other girls or online with them.

My advice would be to talk to him and set everything out on the table.
I have done this with my guy and we're officially monogamously dating. And even though he still texts other girls who are also his friends- they text him & from their end its obvious they want to be more- but he gave me permission to view everything he gets: mail, texts, email, & phone calls. I don't really unless I get a feeling but its nice to know that he has nothing to hide. We talked about the nights I left and he told me what happened with the other girls leaving thinking him being alone would help but it didn't. I didn't realize that it offended him when I left because he thought I was different. So PLEASE talk!

I think he's confused! It sounds like he wants companionship but can't make up his mind - right about now yea your definitely friends with benefits cause he needs cuddling and hugs and kisses - well he sounds like it but I don't know - if you want to do that then no problem go right ahead - yes sure he's seductive but so what - I can find plenty of guys who are just as much as seductive as him - just saying but good luck!
