My relationship with my fiancee is just getting worse and worse. She has been getting alot more upset often. I feel like we get into more arguments or borderline arguments recently too. Im constantly still scared of her killing herself aswell. Today I missed a text she sent, and she instantly assumed im lying and ignored her on purpose. She doesnt believe me at all when I LITERALLY did not see the message. She keeps assuming things about me, or our relationship, and instead of confronting me about it, she instantly gets upset and keeps it to herself till its too late and she is extremely upset and wont listen to a word I say. Im trying to be here for her, the best I can, but everything is going downhill. Everytime im even slightly upset, it ruins her whole entire day and usually ongoing till the next day, mind you, most of the stuff I get upset about has NOTHING to do with her, but she somehow finds a way, without fail, every single time to twist herself into believing im the reason she is upset. I could literally hit my foot on something, get upset, and she could STILL find a way for her to be the root issue. Im not even joking with that either because it has happened muitilpe times already. Im trying so so hard for her, im trying to remind myself not to get mad or upset, and that I need to be here for her. but its SO hard when she DOESNT believe anything I say, twists every problem into her being the cause, she constantly just drowns herself in her sadness and I dont even know how im supposed to help her at that point? This isnt exactly related, but everytime I vent to her, I have to be the one to comfort her. ME, not the other way around, because it always SOMEHOW turns into HER being upset about everything. I literally told her I wanted attention the other day, guess what, she somehow found a way to blame herself for everything and instead of being like "im sorry of course ill give you attention" or "Im sorry im busy right now" she just convinced herself it was her fualt and then I never was comforted or anything and I had to be the one to comfort it. I dont know how much of this I can take, I dont mean that in a way of breaking up, I would NEVER want to break up, but im just afraid its gonna turn into me trying to commit suicide. I think about doing it every single night already. Another thing recently, is everytime something bad happens I get this horrible chest pain around my heart area. Usually it only happened it super stressful and upsetting situations, like when she was moments away from killing herself, but now its becoming more and more often. It even happened practically the entire day yesterday when nothing that upsetting happened. Its starting to appear at every even slightly upsetting situation. Ive never had a heart attack but it genuienly feels like what I think it probably would, I have no idea what it could be either, I told my mom but ofc she dismissed it, and my gf doesnt seem to care either really. Im scared about talking to her more about it because I know she is just somehow gonna blame herself.
