PLEASS HELP,I know this is long but I truly need it. So my bf and I have been together for two years, but before that we were close friends. When we were friends we both liked eachother instantly the moment we met, but didn’t tell one another because I have been seeing another guy at the time but nothing with him was official, but the guy and my now bf were friends. So I continued to hang out with the guy, and he continued to not act like he liked me but we became very close friends whom I would talk to 24/7. On a side note to fully understand the story better, I my self lost my father to suicide when I was only 14 years old, and so I had a lot going on myself. Continuing on, I went through a phase where I would go to a bunch of parties and get drunk just too forget about all the pain losing my dad has caused me and this is what lead to the main event. One night I drank way too much, I wasn’t blackout drunk but I was very out of it and not processing things at normal speed. I finally admitted to liking my now bf to my friends that were at the party with me, whom then told me that he didn’t like me because he told them that he didn’t like me (he now explained to me since that he did like me but thought I didn’t like him so was mad and said that). So I was drunk, I was very upset, I was slow at thinking and understand things, and ended up hooking up with and having sex with the guy I was kind of seeing at the times best friend. I stormed out of the room once I realized to the extent what was going on and left the boy alone, but I understand that the damage was already done. My now bf was there that night and did not take advantage of the state I was in, even though he would’ve liked to have admitted his feelings to me and have hooked up with me, but he knew I was not in the right state to do so. A couple months after that night my now bf and I started dating, and I assumed we never needed to talk about what happened that night because he was there—that assumption was wrong. About a month into the relationship, and we are both completely head over heels for eachother because everything just came so easily with him and I know it was fast but we were so in love already. When he asked me then about what events occurred that night back at the party, I lied and down played everything not telling him what all happened and I said that I did not remember some parts of it. I know that was wrong of me, but I did it because everything was going well and I did not want to upset him and ruin his view of me and our relationship. I continued with this lie until later on I was asked about it again and I admitted the rest, however it was about 6 months into the relationship at this point. He felt betrayed and I have lost his trust rightfully so. Later on, he began to suffer with flashbacks to that night and it really seemed to bother him. He was already diagnosed with anxiety, but it got worse and he became depressed. About a year later he finally spoke up about all his feelings and he was diagnosed with PTSD as well. He says that night is what caused it, therefore making me the root of his problems. We both love eachother so very much and want to be together, but we understand that is going to be difficult. We go through very good times in our realarionship wjere everything is great, but every now and then we have a set back. Just recently everything has been going good for about 6 months now with no set backs at all when he took a turn for the worse. He is constantly interrogating me on what happened, beloved I am still keeping something from him, and says he doesn’t know if he can remain in this relationship and therefore shoved me away. After about a week of only talking when he was yelling at me or questioning me, we finally made up and everything was fine. But then last night, I was very tired after a rough and busy weekend, and he became very anxious and started questioning me again. I accidentally left a minor detail out about what happened and he flipped out and said I did it on purpose and that I’m just like a boy and I answer all his questions to the bare minimum. He said he didn’t talk to me for a week last time, so this time he won’t talk to me for two weeks. He then told me he was sleeping in the bed and that I can take the couch, and to go stay with my mom the rest of the week. I can’t go through this torture of not being there for him again and not talking. He is my best friend and I am his support group, he always does worse when I am not around because he is alone then with no one to sit up with at night if he can’t sleep, or no one to force him to eat and will bring home his favorite food just for this purpose. I just want to help and to some how prove to him that I have told him the full story so that he does not need to worry about it anymore, but I understand that it isn’t my fault he doesn’t believe me. What do I do? Please help, I desperately need it.
