<human>: Give me the gist of the text in a nutshell

I recently moved to a different state for the summer, and before doing so my boyfriend and I separated because of other issues, on top of distance. But, he is still in love with me. And I am not sure if I still am with him, but I definitely have strong feelings for him still. And I really don't know if I want this to be over, *forever*. He's great and I know I'm being extremely selfish. I just have this hope that someday it could work out, but not while I am in a different state! 

I made it clear before I left that we aren't together during this time apart. Since being here though, he talks to me all the time and he still says "I love you" to me and acts like we're together. I didn't know how to deal with that, I've said "I love you" back. Because I did/do(?)

A few days ago though I told him I needed a little more space. And then I had a crazy stupid drunk night and had a threesome. And he is visiting me in 2 days.

I guess my issue is, do I need to tell him what happened before he visits me, so he can decide if he still wants to come? I feel like he needs to know for his own sake/health. He is definitely visiting me fully intending on having sex with me again. Since I've been here he has acted like we didn't even break up. How should I react when he tells me "I love you" still?
<bot>: He doesn't want things to be the way they are, but they are, and I know it's going to hurt him, but I don't know how to deal.
