we're exes of 3 years, all platonic as we's discussed ad nauseum . recently i get her down to my city (to work), she'd always wanted to be by the sea. we move in toa houseshare, get on great, then she starts shagging the 3rd flatmate (a boy). i'm gutted, cos that's not friends looking out for each other is it?
in my confusion i ask her to have me back. it might have been what i wanted one day but not if she's gonna shag 3rd flatmate under the same roof, take away my safe home. I knew it wasnt what i wanted, so i tell her i was confused. still am so upset that she could have done that, knowing it would have hurt me. trouble is, i now know she's not the kind of frriend i thought she was, i don't hold her in the same regard as before, and it's time to sever contact. she's hurt because i went out with her briefly this time, but it was with wonky head, caused by her.
i'm just overwhelmingly disappointed that she's turned out cheap and desperate. i dont want to hurt her feelings but dont want to hang around to get more hurt by her. how do i tell her?
