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

First and foremost - I'm not looking for judgement or criticism. I'm looking for constructive advice. I also realize that my feeling like this probably makes me seem like a bit of a crazy person, but I invested an enormous amount of myself into this relationship and and am struggling with moving past it. Here goes...

Long story short - BF (of just over 1yr) and I broke up (mutually) last week. Still live together and are remaining friends (living together because he can't afford the apartment alone and I have an eviction on my record so I can't get a place of my own). It was bittersweet. We love each other but we're just too different to work out as a couple, in the long run. I'm sad about it but I know that it's definitely for the better.

So here is what I'm currently curious about....
I know he's talking to this one girl in particular (amongst others) we both know who is known for being a MAJOR slut - causes lots of drama - etc.

I don't know why it bothers me - especially because she...
*Lives in not only a different state but a different time zone
*Is in a relationship with someone else (And is Polyamarous - both reasons why he wouldn't want to be involved with her as he is monogamous)
*He's totally oblivious to the fact that she's constantly hitting on him

I'm ok with him moving on. The idea of it makes me sad but I want him to be happy above all else.

I don't want to be upset about this. Can anyone offer advice for coping?
<bot>: Ex-Bf is talking to other girls and seeing it happen is incredibly upsetting. I'm in search of a means of coping. Creative Advice Welcome.
