<human>: Can you provide a brief rundown of the text in within 3 sentences?

We broke up a month ago, and it wasn't hard. We both knew that it was going to happen. We still hung out, we did things together, hooked-up, made out, did things a normal couple would do. 

I went home to see family and friends and that's where things started going down hill for me.She was telling me she made out with friends, but that's okay. People make out, and we're not together so its okay.

We got over it, we talked, things started to feel normal, it felt like things were getting better.

I went out a week after, I get texts from her saying not to do anything with anyone else. She missed me. She called. I didn't answer. I followed through with what she wanted and didn't do anything.

The day after, I get a text early in the morning. I knew. She had a one night stand. She went back on her fucking word. She fucks another guy, and I'm the one looking like a fucking idiot. I still can't get over it. I've been having bad anxiety, I can't eat, sleep, my relationships with other people are going down the drain. I don't know what to do. I think about it all the time. I know I shouldn't but I just do, and it's hard not to.

Don't get me wrong I love her to death and she is an amazing girl but that hurt my feelings so much. It's now making things so much worse, and I can't shake the feelings away. I feel like a toy, that she can use me whenever she wants expecting me to get the same answer over and over again.

What should I do? She talked about one day getting back and I do want that and I feel like she does too. I know that there should be some definite space, but what can I do to get my mind off things? 

I'm having a hard time typing this because as much as I want comfort, it's killing me and I can't rid of the negative emotions that I've been having.
<bot>: Ex-Gf tells me not to do anything with anyone while I'm out. She has one night stand next day. What should I do?
