Hello Reddit. I am in need of some advice. I, 20F and my Girlfriend 20F, have been having some issues. We have been dating for about two years, and have known each other in passing for much longer. Here is my dilemma, me and my GF have been having problems in our relationship. I have been sexually assaulted in the past, and sometimes I struggle with feeling uncomfortable with certain forms of affection (not all the time). I have communicated this to my GF, and slightly to my peers. My GF has been having some issues lately because she is a sensitive affectionate person, and we have gotten into slightly heated conversations about how she feels unloved and like she cannot touch me anymore. As well of that we are more like friends, then partners. One of our friends (lets call her Mary), was talking to my GF on a night he was upset about how I need to step back and evaluate myself because of my previous trauma. Mary was saying how I was comparing my GF to my ex ( who assaulted me), and how it was not cool of me. However, i am confused on how me informing my now GF when i get uncomfortable its because of my past ex is comparing the two of them. I am struggling to understand how my past traumatic experiences make me have to automatically not have any momentary touching boundaries. For context, my girlfriend is a bit insecure because of other things as well. We have a person in our friend group, lets name them Jocelyn. Jocelyn gets extremely uncomfortable and rude to the both of us when we are slightly affectionate in public, we have talked to her about it and she does not care. I have subconsciously stopped being affectionate in public around her and my friends, and that is contributing to my boyfriends feelings of being unloved. Reddit, some advice please? Am I the problem? Or is it my friends? Or everyone? Im really struggling, with my friends shouting at me to breakup, as well as them telling me to stop being affectionate, its really impacting the health of our relationship. It upsets me, because it feels like I cannot have boundaries in the relationship, and that everything I have been through is my fault. I am medicated, as well as in the process of acquiring therapy.
