Honestly don’t even bother reading this, it’s a waste of your time,seriously.

We both have our share of mental issues, but mine are ruining our relationship half the time. We’re perfect for each other in every way. We were long distance for 2 years before I moved in with her 2 months ago, and I’ve never been happier, but every time I have a bad day, I end up doing something or acting some way that hurts her feelings. Sometimes I don’t think the actions or behavior I have are hurtful to the extent that it seems, so I ask her why she’s hurt the way she is and I don’t understand it and argue. We fight and I end up calling myself a piece of shit, which gives her an anxiety attack. (I’ve threatened to kill myself before and she gets anxious whenever I talk badly of myself during arguments.) this time I decided to leave the room as she tells me to stay, and that I’m not considerate for leaving her when she’s asking me to stay. I usually stay, but I also feel that leaving could make her feel better, as when she’s anxious, touching her makes her even more anxious, and she tells me not to touch or talk to her, so I’m in the living room writing this. Here I am, young and with the love of my life, as I continuously hurt her and ruin her life as I act normal to my standards. I want her to break up with me so she can live a happy life with someone better, and so I can gladly end mine so I don’t ruin anyone else’s.

tldr for anyone who ignored my memo, 
I suck, I make love of my life anxious and sad, I want her to have better partner, and I want to die because I can’t be that partner.
