Hi I have been with my fiance from September 2014 till now and we have got engaged in February so we've been engaged for 6 months. He and i had just gone out of 5 year relationships. I just found out that he has met up with his ex in november, October 2014 which is us being together for 2 months. Apparently she had forced him and threatened him to meet up with her because she's always suicidal so apparently he got scared so he met up with her. Her ex has tried committing suicide before and was hospitalised. I also found out about an email that was sent by him to his ex only 2 weeks before we got engaged. In this email it's written that he misses his ex and his always thinking of her, his upset that he has just left her and that she shouldn't worry as me and him are broken up. I classify these both things as cheating on me . He says that he did not write that email to her and he reckons she has played around with his email account and sent her self typed up messsages. And I don't know if I should accept him in my life and have trust issues for the rest of our lives or let go of him now. What will be the most ideal? Is this cheating and does it still count as cheating if he was scared of her killing herself?
