We are a long distance couple. I helped my ex pass his exams by sending him some resources and sent him money to get food. At the time of helping him, I didn’t even consider the fact that it was my ex, I just thought oh it’s someone who needs my help badly. When I helped him, I mentioned it to my boyfriend just as part of our daily conversations like “yes I had a good day, work was fine, I helped a friend pass an exam and sent him money because he really needed it”. I realize my mistake was not disclosing who I helped completely. Last night, this conversation came up with my bf and I said yeah he was someone who I had a past with. My bf is so very upset and I understand that, but he compares this to cheating. He said “if I go around sleeping with another woman and come home, would you accept me?”. I never physically cheated. My intention was not to hide anything in the first place. I just wish I clearly mentioned who I helped. I realize what I did is terribly wrong. My bf doesn’t trust me anymore. How do I gain back his trust?
