<human>: Can you summarize the given text in a few sentences?

so ive been in all sorts of relationships (uncommitted, committed, living together, LDR, off/on, open, etc) with this guy for nearly 8 years. right now we are "just seeing each other". basically we go on a date and back to his house every saturday until he has work sunday afternoon. 

we're young so we've agreed to not be tied down and fight over stupid stuff and it's working for the most part, but hs trust issues are killing me! I've only slept with 3 people in the last 4 years only him for close to 2 years), but he'll never believe me. 

he also has a problem with me having nice things. eveytime i have my nails done i'm accused of trying to impress someone else because he doesn't like them. everytime i buy a michael kors or coach bag, he says "what guy bought you that?" he accused me of getting my diamond tennis bracelet from a guy. I CAN'T HAVE NICE THINGS OR I'M A CHEATER! I'M GOING CRAZY. i use shopping as retail therapy. no, i don't have any credit card debt or use money i don't have. 

i'm also not allowed to talk about things i do when he isn't around for them. so i can't mention anything that i do. i went out to eat alone and told him, but got accused of going on a date.

i'm so confused. i know he loves me. we we're fighting recently through text and he walked out of class to answer my call. he also was late into work because he wanted to make sure i was okay before he went in. he tries to be considerate of my feelings, but the whole reason we're not committed right now is because he doesn't believe i can be.
<bot>: can't handle being accused of shit all the time. im not even allowed to talk basically. how do i tell my partner to chill out and stop the crazy accusations?
