Hey /r/relationships 

between christmas and the new year my former gf of 2 years broke up with me. The reason for this is more or less because she feels, that she is too young to commit into something serious and that she need's to sleep with more guys first (this is something she said, i am not making this up).

We lived together in a small flat for 1,5 years.

 We have the same job which is a combination of working (at different places) and attending university for a few weeks straight here and there (this will be when we see each other again).

She has been a part of my everyday-life, my job-life, family-life, hobbies, things i like, and everything i can think of. Now the fact that she want's to fuck around in our flat...my bed...while i still have to see her sometimes is killing me.

I know, what ex's are doing is not my business, but how exactly can i stop those feelings? Stop being hurt? Even if i can manage to forget her, i will always have to see her again and will be reminded of the past and that she is now sharing all the beautiful things with someone else and i don't know how to move on because of this situation. 

I really need some help.
<bot>: Broke up with ex because she wants to pork other guys, have to see her again here and there and can't move in because of this. What to do?
