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

Basically, my girlfriend of 3 years broke up with me around Christmas, after moving in with me. I offered for her to stay because I knew she didn't have anywhere to go and her car was busted.

I've done many things to make her feel comfortable and to make her happy...probably way more than an ex boyfriend should ever do. She's been very friendly towards me the last few weeks. We've gone out, watched movies, dinners, hang out at home...pretty much everything that a couple does. Recently, is gotten to the point where she's wanted to have sex...and we've done it. I know, not a good idea.

At first I was enjoying this but now a month in, I realize that she's basically getting to date me without giving us the title or me the commitment. It's not fair. I've thought about this enough that my feelings for her are slowly starting to fade away and I'm beginning to resent her, which I don't want happening.

I don't want this going on much longer. Should I confront her and ask her to give us another chance? Should I tell her we need to stop being so friendly? 

Her moving out is still out of the question, atleast for a few more months.
