My(25M) GF(24F) Cheated on me with her ex and today won’t move out

Lately found out my gf associated with over a year has been sleeping with her ex for some time now. This all occurred on the last night of a vacation I took her upon across the country for a wedding inside my family.

It took me hours to pry this information out of her, and then I dug into her telling the girl how fucked up this is and how much pain it is causing me, even after her ex cheated on her prior to we met.

Clearly We don' t want to be inside a relationship with someone that has no respect for me, so I asked her to move out of our apartment. At first she was going to, but now she' s telling me that she has the right to stay here and that we are just going to be roommates for the next 5 several weeks.

This is something I' meters not okay with. A person chose to cheat, you knew the consequences. I don' to want to move out, one due to the fact I make more money than her, two because I found the apartment and she would generally complain about things about the apartment.

Now I' meters just looking for some suggestions about how to handle this situation. I can' t continue to online along with her much longer. It' t just going to eat away at my mental health the longer this drags upon.
