So last night I found out that my boyfriend of 2 and a half years made out with one of my “friends” almost 4 months ago at her 18th birthday party, after I had gone to sleep in the other room. I honestly have no idea what to do. Ever since the party, something has been off with him and I knew it was. He promised me nothing was wrong and I believed him. This “friend” has been nothing but bitchy towards me and treats me as if I’m worth nothing, constantly putting me down to not only my partner but to my other friends, but it makes sense now why. All these little comments and actions make sense now. I am completely broken at the fact that she has had a part of me that I never thought anyone else would ever get and I’m more broken that he has lied to me for so long. I completely love this boy but I have no idea what to do. If he really loved me to begin with, would he have even done this? For the whole relationship I have been nothing but faithful to him and don’t know what to do about it.
