<human>: Provide a brief overview of the text.

When we first hooked up it was great, incredible sex, leave each alone the next few days, then do it again. Eventually we start to do more, going camping together, hiking scenic mountains, long road trips. So I started to want more, and clearly stated such. She said she wasn't ready for a relationship, and asked if I could give her some time to figure it out. I obliged cuz I'm dumb. 

In April we "broke up" after a getting drunk at a concert, and into a fight afterwards. We had break up sex, and she told me to stay the night which was fucking weird. We talked it out a few days later, and she said she was just drunk and knew I was still looking to be her bf, but she was frustrated because she still wasn't ready for it and didn't want to bring me down.

Breaking up with her made me question if I wanted a relationship with her, so I was back to a casual situation. After we again started messing around together I made her promise to share any feelings she had for me openly, and I'd do the same. 

At her 25th birthday party 3 weeks ago,  she treated me like a bf, introducing me to her friends, kissing me in front of ppl, cuddling me, cooking food together, and I gave her the usual birthday treatment. Which was fucking horrible because all I could do was think about how awesome it'd be to be with her. So I'm back in that mode. 

We haven't had sex since her birthday. And I've been away on business and haven't seen her much. I feel like I need to tell her I again want a relationship again now and ruin all the good things we have together, because I'm fairly certain she doesn't want the relationship and will turn me down. I just want to get this off my chest to the world, and here some advice.
<bot>: I'm thinking it's time to give a relationship ultimatum with the quasi gf, that she'll probably reject, thereby making me life less fun.
