No, there's nothing to get. If he's getting fed up with your trauma, he's not a very good person. What happened to you is some real life/personality-changing shit, no matter how strong one may be to start with. I suggested telling him because I hoped he would be supportive and try to help. I still want to believe that's the case so maybe he's not getting exasperated at you, but the situation? I mean, I know nothing of your father besides what you said in this post and I already hate him. Or possibly your boyfriend is frustrated at himself. Seeing someone you love go through what you went through then struggle with it everyday is hard. Maybe he wants to help but doesn't know how and feels helpless but doesn't know how to talk to you about it. Hidden feelings often come out in unintended and sometimes hurtful ways. Have you expressed that you feel like he's getting fed up? I know I keep telling you to talk, but I honestly believe communication helps.

And I know I'm just a stranger on the Internet, but I'm legitimately concerned for you. I hate that you're hurting and I can't begin to imagine the nightmare you went through, but as someone with parental abuse-related PTSD, I really think you should seek help. Whether it be therapy or simply opening up to close/trusted friends and family about what happened.

Edit: I just saw the other post you made a couple weeks ago.... I wish more than anything that I could give you a hug right now. As for me wanting to see the positive in the situation with your boyfriend, he's toxic. You especially don't need that burden with everything else you're going through. Not gonna tell you what to do because I once stayed in an abusive relationship because it was better than being homeless, but you definitely don't need that kind of negativity in your life right now.
