Also, for me it was super difficult for me to break away from my ex alcoholic bf. Mainly because I had witnessed him close to death from alcohol so many times, I drove him to the ER, when he was stuck on these insane alcoholic binges.--
I was presented with similiar shocking information (that he was seeing another woman), and finally took this as my ticket. I did thank god manage to break all contact with him--I missed him desperately at first; I truly hated to give up after all we had been through, but was also shocked as to how much calmer my life became (almost immediately) once he is no longer a part of it.
