Can you please give me advice on my friends with benefits relationship?

I recently saw a friend of mine I hadn't seen in a few years at a party and he ended up spending the night at my place and we had sex the next day. I've been talking to him online and on the phone since, but he's been mentioning other women that he likes. I'm assuming this means he doesn't like me, yet he extended an invitation to me to come over to his apt anytime I'd like and that he's really trying to move on from his past failed relationship. Is he trying to make me jealous or is he really not interested? He is relatively unstable emotionally and has a lot of issues, and I've always been there for him. He calls me when he's in trouble or needs emotional support, I've known him about 6 years. I love that he trusts me and feels open with me about his feelings, but is he just using me? I feel like I'm always there for him and I really care about him, and I don't know how he feels about me. I'm scared to bring it up with him and we both are acting like nothing happened. Was this just a one time thing? Have any of you been in a situation like this or have any advice as to what to do? I'm nervous to see him as I'm not sure if he's expecting sex...it really was great, but I'm scared of getting hurt :(Can you please give me advice on my friends with benefits relationship?
Hey. I was in a similar situation. I don't think he is trying to make you jealous. Guys are complete idiots sometimes. I'm willing to bet that he has NO clue that you feel the way you do towards him. Even after the fact that you guys slept together. Now days people can have sex without having feelings for each other, h*** you don't even have to know their names these days. I think he is likes having you around too much, he knows that you'll always be there for him. And now that he knows he can get more from you in a physical sense....all the while he's in between females. Hon, I think you guys should talk. Tell him how you feel. After a while it'll get old....if it hasnt already....and it'll just completly destroy your ';friendship';. Best of luck.Can you please give me advice on my friends with benefits relationship?
My personal Experience is same but I am a guy. We had sex even when my friend knew that i m dating another chick. It happens when thought of sex drives u crazy. if u enjoyed sex with him before then go to his apt. But if we guys share our emotions with someone, then it means that we really like them as our friend so it doesnt mean that he is using u.
Sounds like he likes you and likes having sex with you but doesn't want to be your boyfriend. If you are looking for a relationship, you should be looking for someone else.
