So,
I gave my ex a second chance and it didn't work out (as most of you predicted

)
We both did our bests but in my opinion she has some deep issues that just don't make her capable of having a stable serious relationship.
After another set back I was just really done with it and we decided to break up.
She understands but asked me if I wanted to have a platonic relationship with her because she doesn't want to lose me. She told me I could see and fuck other girls, so she had the space to work on her issues. She also told me she wouldn't be allowed meeting other guys in this scenario. Also, and that really surprised me she asked if she could explore her sexual desires with other woman in this "agreement". I asked that if I would agree I could join, to which she replied she didn't want to see me fuck another girl...
So to be honest I was really mind boggled by this and have no idea what to think of it?
I already declined because I don't really have any interest in her anymore and believe I deserve a girl of higher quality.
Also staying in this relationship would just keep frustrating me over her behaviour, issues and I'm just to emotionally invested in this girl to not give a fuck...
But seriously, why would any woman want something like this?
Thanks!
