AITA FOR TRYING TO REDUCE CONTACT FOR GOOD PURPOSES WITH MY FRIEND?

ok so I'm a 19yr old gay boy and my friend too is 19yrs old. We met at 2018 and we were like half friends since then till 10th grade but it changed last year. I hid my real self and suppressed my real version in 10th grade. 2024 happened and we met at a cram school. I opened up to him and revealed my real self and this January it was his birthday,I had an important exam and forgot its his bday and told him to go to bed instead in his DMs. He got angry saying he was waiting for someone to wish him and called me a betrayer and had a huge fight(the context of the betrayer one is his childhood crush turned girlfriend left him and came back last year and they dated again and when she left him he was really hurt and he has trust issues now I broke his trust for forgetting his birthday and I'm a betrayer and I've told him ill never betray him). Me revealing my real self and him also sharing his past stories made me attached to him and I thought of him as my brother who i should always take care of. I told him some events that happened to me and a story about his girlfriend too and he ignored my stories and listened about his gf only instead. Idk why but I was deeply hurt by that and later we talked things about me getting attached to him and he said not to get attached and its also weird how I'm attached to him without having any romantic feelings for him. I'm a yapper and sometimes I yap unknowingly which triggers his insecurities which im very regretful about like I compared him to a game character having abs and all.Then one day I shared a thirst trap about another character and he said not to send things like this and keep some things to myself and control myself. I realised i was getting too attached so I made the decision to reduce my contact with him and I kept his message on read and next day he called me a very high demand person cuz I ignored his text AND I BECAME ANGRY AT TAHT CUZ I WAS TRYING TO REDUCE CONTACT and he ignored my msz too first but i didn't think anything about it. We haven't talked since that day and I've gotten really sour about him and now i think "why is he not saying anything to me he clearly knows I'm angry?can't he ask if something happened? Was our friendship timepass to him?" Its sad cuz I was always there when he had problems and I for ONCE want him to ask something wrong instead of me always saying"so something happened.." Now he's all cheers and just being cheerful with his friends (i don't have any problems about this) but did he see me as a replaceable friend?its like I didn't exist at all and tbh I'm a person who adjusts to a certain level and being with him, I've to always walk on eggshells which is good for me or not I don't even know. I'm hurt thinking how I always helped him immediately when something happened but when something is wrong with me, he didn't even bother me to ask. AITA for trying to reduce contact??
