Hi, I don't know if this has to do with anxiety or something else so I will tell you a story.
I am in a relationship with my boyfriend for 4 years now. At the beginning of the relationship, 3 weeks in, I kissed someone else and didn't tell my boyfriend until 3 months ago. He was hurt but we stayed in relationship and after a month he told me that he totally got over that and that he is sure thet he wants everything in life with me. I was relieved and I am so happy in this relationship but I am scared that I can hurt him again or that someone else would hurt him by bringing that up. I don't have direct contact with that group of friends but my brother does, not particularly with that guy anymore but with the people that were the part of that friend group. I make these scenarios in my head that someone would tell him something or that he would for example work with the guy or some people from that time period and that someone will bring this up. I don't know why am I like this and why am I even make these scenarios in my head when he forgave me and we moved on 2 months ago. I don't know how to stop this feeling. My mom said to me that this is stupid and that I have to move past this because no-one even remember this and if they does it is stupid to bring this up after 4 years or more. She said to me that life goes forward and that I can't be scared about everything and everyone and that even if I didn't tell him for my cheating I had to get over it long time ago. For some reason I feel like this isn't even about this thing and it is about my anxiety and low self esteem... I don't know what to do.
