<human>: I{29M} confronted my GF{22F} about her feelings for her ex/coworker. She admitted to being in love with him. They are constantly texting each other at all hours. He has posted quotes on Facebook like "she is too much for one man, but not enough for two." I asked her to decide who she wants to be with and if it's me to stop contact outside of a professional work relationship. 

Background: we have been off and on for 3 years now. And every "off" she get together with at least 1 other guy. I have been with just her for the last 3 years, just because I can't move on quickly I guess. The last off she hooked up with her coworker. That lasted for about a month before she moved into my apartment, and we where back on in my head. 

During the talk she admitted that if she feels I am not giving her the attention she needs then she feels no remorse getting it elsewhere. After all was said and done she said she would let me know what she wants. 

It's been a week and she has not said anything. I don't know if I want to stay with a person that takes this long to decide who she wants to be with. 

Should I just give up, and ask her to move out?

Can you condense the text into three sentences or less?
<bot>: my GF loves someone else and won't decide who she will be with. It's been a week. Help me!
