My friend has been dating someone for a few years who I feel is not single. When they originally met this person said they were recently separated etc etc however years later this person is still in regular touch with ex-husband, attending functions together, short trips, school events etc. My friend has yet to have this lady spend a night with him, introduce him to any of her family or friends or basically act like they are in a relationship in the open. I have said before that I didnt think she was completely single but to no avail. I also believe that she has had other "mini" affairs whilst with my friend.
This lady has gone back and forward to her dh for many years, wherein the dh will be aware that she has met someone else, that relationship comes to an end and off she pops back to her dh.
My friend has left and gone back a few times but most recently decided to leave the relationship for good. I was very direct this time about my feelings. I told him that she was basically having an affair - she has had previous affairs and although she was telling my friend she was separated etc I could see no difference between her previous affairs and what my friend had with her. My friend has become very angry with me - in fact vented quite strongly and accused me of being too invested etc. I honestly cant look at him the same. Ive told him that im so angry and upset that after listening for over 4 years and trying to understand that his attitude is to attack me when Im honest with him.
He has tried to make overtures to me, thanking me for being there but Im just done. His attitude to me has shone a light and I feel like he has been using me for help and to offload.
I feel so guilty though. AIBU to just end the friendship. Ive rarely gone to him with any problem Im having as his life appeared so stressful and now Im just done.
