I’m 21, fresh out of a 3.5 year relationship. She was my first, I was hers. She betrayed me, so I had to leave. I still miss/love her.

The issue is that I feel like I’m somehow doing something wrong by speaking to other girls. How do I get rid of this mentality?

I was fairly blue pilled prior to this relationship (I thimk this contributed to her looking for validation in other men) and I am working on fixing myself and becoming better each day. However, the above problem is a strange feeling that I do not know how to tackle.
