But more of that I love her and I mean what I say when I tell her things. Earlier we were talking about when we should get engaged and I have a lot of financial issues I want to resolve before getting engaged, but the only thing that stuck out was that I "wasn't ready to commit to her" and she interprets everything I say as reasons I don't love her whenever we have a disagreement. It makes me feel she doesn't trust me and only wants to see things her way and lets her emotions get the better of her.

We have a very healthy relationship otherwise but she's extremely sensitive. One time I was a little irritated with her while I was busy working and lightly shoved her when she tried to hug me as I was doing the laundry while arguing with my mom, and she immediately started sulking for hours and avoiding me. Later she said she was afraid to talk to me and didn't know how long I wanted to "punish" her for. Another time we had a fight late in the night and I was taking space the next day, she was talking to a mutual friend and genuinely seemed to feel like there was a chance I would ghost her just for that.

It's so hard to see. She loves me like I'm the entire universe but finds it so hard to accept love from me or trust me not to leave her at any moment.

tl;dr: partner is afraid i will stop loving her the instant it's not perfect
