My boyfriend, whom I've currently been with for a year and 4 months, flirted and led on another girl, who used to be his ex. This happened a while ago. Around November up into mine and his one year. We started dating December 14, 2011. However, when I found out on our 1 year, he denied he was flirting with her and that he was just talking to her and giving her support. This girl just recently sent me pictures with proof that he did indeed text her and message her. He reactivated his Facebook several times to get into contact with her and sent her numerous emails (according to the messages he sent her). But he hasn't talked to her since December, our 1 year. So I just have evidence that he flirted with her about 4-5 months ago... When I showed him the pictures, he said that he does not remember sending them... I don't know if I should forgive him or not.
Also, he is diagnosed with schizophrenia. Which may add to the fact he does not remember doing this.
I'd say it's really your choice honestly. If you see yourself being able to forgive him and learning to trust him again then that's something you're putting yourself through for him and you should only do that if you feel he is worth it.
However I don't think you should. Even if he may not remember doing it, the point is, he did it. Fact of the matter is, his memory doesn't affect his judgment in the slightest and if he did went ahead and did that he did that knowing full well he was with you. That's why I think you shouldn't forgive him.
However, it's your choice to make not mine. You know what I think, now it's time to arrive to your own conclusions and decide what it is that you want to do with him.
Good luck and I hope it all works out the way you want it too :)
The real question is, is he using his schizophrenia as an excuse to behave poorly or is he being honest about not remembering it?
Once you've sorted that out, you can then determine whether or not this relationship is worth the trouble. Schizophrenia is a very difficult thing to cope with.
You should not forgive him. You have already given him chance, but he could't hold it well.
