So my ex-boyfriend and I broke up a few months ago, well he did the dumping actually. But I'm still in love with him. And just recently, we've been reminiscing about the past. Just a few days ago, we met at a mutual friends' house (it was a get together actually), and we started talking, and took a walk together... we made out, and went beyond that also, exploring each other just the way we did when we were dating, and it felt so good.. it made me so happy. We planned on hooking up tomorrow. But I want more than kisses and touches, I actually want something real. But it doesn't look like he's up for anything emotional, and this might hurt me a lot later. I know it's wrong but I just can't say no to him, because I cannot bear the thought of losing him. So what should I do? Because I know that he doesn't feel the same way I do, and he just might be using the fact that I'm there whenever he wants to do anything sexual. And I know that for a fact there are things that's going to happen between us

Then use your head and not your emotions and hormones. Don't allow yourself to be used.
