I'm in a very happy and committed relationship but now my ex the girl that I was madly n obsessively in love with started texting me and reaching out to me. and I don't have the same feelings for her as I used to but now all the old memories of us is coming back and I don't know if I should tell my boyfriend that she texted or if I should keep it to myself. I don't want him to think that I want to go back together with her because I don't. I love him and I want to be with him.
