was it my fault for reacting badly to these things?

I tend to be very emotional. I did have insecurities for sure but everything was fine externally and there were no arguments until I found out he was doing certain things. do you think things would be different if I was just more calm about how I talked to him about stuff? did I have too high standards??? we’re over now and i’m genuinely asking bc I feel terrible and my brain is telling me it’s my fault and it could’ve been better if I wasn’t soo sensitive or argumentative or reactive. I listed all things we argued about. there were literally no arguments other than this. and other than these stuff he treated me so well. we had really good times. yes i’m young, yes he was older than me, no I won’t go back to him, and yes, i know i should’ve left the first time I felt unappreciated, but now I just feel like somehow it’s my fault bc of insecurities and anxiety and overthinking? cus that’s how he made it seem. like I blew all of this out of proportion and that I wasn’t ready for a relationship cus of how I reacted negatively to these things. I would never raise my voice or anything but i’d cry a lot. and then sometimes i’d bring these stuff up outside of arguments and now I see how that could annoy him. I ended it, but he said he had lost feelings before I ended it because it was getting too stressful for him bc of my insecurities.

okay the causes of the arguments:

- him liking and following specific types of content. I had to ask him 4 times to stop and threaten to leave before he actually did. But to my knowledge he didn’t continue after that.

- him looking at other girls while we were together

- He said the n word. he’s white. I was uncomfortable with it and had to ask him to stop 3+ times before he actually did. he actually apologised and never said it again (in front of me).

- he lied about some small things, which made me think he was lying about other things. He swears down he’s never lied other than those times but how can I actually believe him. So that caused trust issues. and ik that talking about my trust issues sometimes could get annoying and I really tried to stop but I didn’t want to feel taken advantage of so I felt like I had to speak up about what was bothering me.

- he had a sex addiction. I was willing to help or get him help, but he didn’t want to see his problem and would rather leave than get help.

- punched a hole in the wall when he got angry at his mom

- couldn’t save money

- always walked in front of me rather than beside me even after I asked just so I could hold his hand

- when we became single he with quickness added all his old flings back, added new people and immediately went to looking for someone new. he told me that his ex sent him nudes. made me think he was in contact w her the whole time we were together.

we don’t talk anymore now. I got a therapist and I know I need to work on my self worth so I won’t be so insecure if I get in another relationship.
