Ok Recently in the beginning of the year I separated with the mother my child after six hard years I called it quits I still see my daughter but Im going through a lot custody battles mean while my best friend of ten years also had broke up with her ex a couple months before me. She has been there for support and just been my rock so a month after me and my ex broke up, me and my best friend hooked up 
It was awkward but it we agreed it felt right. So as time went on things were good until we got into a little fight and her ex came in her life pleading to get back with her but she says has no intention of getting back with but she still to be his friend because she feels he did a lot for her she feels guilty. Strange right... Just recently there was a big thunderstorm and the roof of her bedroom fell off and she has been living with a friend for about year and she feels it's time to move on of course I offered but she feels that my ex is phsyco and she doesn't want to be labeled the girl that I left my mothers daughter for so she feels it recent. So her ex offered and convince her that there more job opportunity and she would be able to finish school faster and that he would not try to do anything funny so she's  thinking about it but thank god her dad let her and her son move in. Well it didn't even last a week at her dads because of the step mom so she's back at her friends and now had decided to move in with her ex in a city 150 miles away. She does has to come every other weekend so her son could see  real dad and tells me she would stay and sleep at my place when she does come down and during all of this I've kept my cool but yesterday I told her if by any chance she wants or does get back with her ex I'm basically ending everything with her even the friendship it's hard but that's just how I feel can somebody give me opinion please
