Honestly? Until he says otherwise, assume what he has already told you is nothing but the truth. If it turns out he has changed his mind, he will come forward in his own time and let you know. If he hasn't, and you continue to believe or suspect he has, you are only setting yourself up to be hurt once it finally sinks in (or, worse, blows up in your face).

Take some time to evaluate what it is you truly want. Do you want to spend more time on a "maybe", that has a high probability of hurting you the longer it goes on for? Or do you want to explore other options in hopes of finding someone who is genuinely interested in something more with you? These are the things you're going to have to figure out for yourself - and with all those pesky "emotions" in the way, coming to a conclusion is not going to be easy.

It seems like you really need a definite answer before you are able to move on. It's borderline him leading you on at this point it sounds like. He doesn't want a relationship, yet his body language is saying something completely different. Not to be too hard on your friend, but that's not quite fair to you. It's hard to tell if he really knows how you feel or if he's assuming that you're just being nice, and feeling the same thing he is. (Just enjoying friends with benefits) I've come to the conclusion that it seems like a lot of guys are on a different level than us ladies, and sometimes they need a bit of help understanding us. The best way is to be blunt. I say, tell him how you're feeling, and have him tell you plainly that he isn't wanting a relationship. And if he isn't, then you may need to take a step back, and not allow him to treat you like a girlfriend, because it's just going to leave you longing for something that may never happen. Staying there, and being friends with benefits while you're falling for him, is going to hurt just as much as telling him that you need a relationship, and can't deal with just being friends with benefits. He may need time without knowing that you'll always be there to be his friend with benefits. If you need more than he is giving, then you shouldn't make yourself stay around your friend for the hopes of him wanting a relationship with you. You may be missing the one person who will make you even happier than this friend is currently. I hope everything works out, and I beg you, to put yourself first. He sounds like a great guy, but don't let him hurt you. And don't let yourself get hurt worse than you will. You deserve to have the relationship you want AND need.

I agree with that ultimately talking to him is the best option, but I think you first should be certain of your feelings towards him. If you're certain of your feelings, bring them up to him and see what he thinks and be mindful of his reaction.

Remember to think about yourself and what you are feeling first, before you think and worry about what he is thinking and feeling.
