You posted this about a month ago and got excellent, thoughtful advice. These posts should be combined. Repeated postings don't necessarily get different or better answers.

I'm not sure I can offer good advice here but maybe try watching how your partner reacts when you do something nice for her and take enjoyment/ pleasure in that instead of expecting something in return. Ie: relationships are not necessarily about you do something for me and I will do something for you right? There is definitely a lot of pleasure to be had by helping other people and making them happy.

Maybe try to chill out a bit generally and take jokes as jokes. I know that's hard sometimes though.
