Hello, I hope this is the right subreddit. (LONG TXT)
Context/background if important: I (30)just got out of an 8yr relationship and the main reasons (according to my bf(37)) were: He no longer loves/cares for me, I scared his heart beyond repair not even prayers can fix it, he'll never date again bc of me, and bc of my selfishness that I had displayed previously for many years.
I was told he was "Blame Dumping" as I basically raised my bf (helped him get a state ID, SS Card, Bank Account, Job) everything he owns game system wise/games were bought by me, he was on my Nintendo Account for free for the first year I added him to it, I also bought him his FF7 coat, bought him "Best BF" trophies/medals, I put him above my own feelings time and time again even while I was depressed and suffering personally, I've kept 3 of his darkest secrets from his past hidden (and still am!), I stayed by his side through every single failure and hardship too.
Even at the end I made him a Spotify "positivity" playlist to help him with his depression/self hatred, I even gave him a heads up that I removed him from our NSO and that he owes me nothing for payment even though the $80 had already been taken out this month. So I personally feel I went up and beyond and wasn't selfish. However, him blaming my selfishness really got to me so I did some self reflecting to see if I truly was as selfish as he made it sound. This is the list I came up with and I was hoping y'all could give me some advice on how to change these areas of myself(I'ma Christian if that needs to be said):
Put my jealousy into words and explain my feelings. I lash out to cover up the fact I'm actually jealous. I say hurtful things and project my insecurities to cover up my feelings vs just explain them like a mature adult.
I am very protective and untrusting towards others with my music/videos on youtube, this should change with My boyfriend at least. (I have had people in my past not respect my religion and show me songs/videos with swearing, rap - I just dun like rap, scream-o and things that were very against my beliefs. So it became a defence)
I need to delete/block contacts that are ex's or friends who come off like they have a thing for me. I struggle with this as I like knowing someone out there loves me, and the attention I got. (I have started this one and deleted all ex's and told a friend who kept flirting with me that I didn't feel the same and wanted space from him)
Stop projecting my insecurities when angry - being cheated on, being broken up with for not being good enough, being poor, etc
saying "whatever" needs to stop. Like "It's whatever" it has been used to hide pain but comes off as anger. It being used in anger also needs to stop. I should properly say my feelings like a mature adult vs like a teenager.
Don't use the "ur abusing me" tactic during an argument, it just hurts the other person or makes them more angry.
Take more interest in things I don't like when it comes to others, I usually just tell the person I'm not interested in what they like bc I don't want them wasting their time.
Instead of saying "you should/shouldn’t have done it this way" I will now say "would you like advice on that?" Or "What lead you to make this decision?"
I will no longer bring up flaws, point them out or say how they make me feel. I'm very "now" and get impatient when someone is working on a flaw that is destructive to our relationship. I must be patient, kind, understanding, supportive and step back when I want to focus on small things.
I MUST stop bringing up Divorce/Breakup when upset - this is more damaging than helpful.
How can I go about changing these areas of myself?
