I love my GF (19F)so much but sometimes I feel like its best to let go (18M)

Weve been dating for almost 3 years now and I love her... she is smart, gorgeous and funny but sometimes I wonder if its really worth it, every once in a while we fight which is normal, but the problem is she never wants to solve things in my way and always does her way (although she denies to do that, she never talked about me this type of stuff face to face or in a phone call which is what i prefer to underatand her better she only want to talk through texts on this fights otherwise she would get too mad and break up with me, i dont know how to word it any better she literally said that last part sorry if its a little confusing my head is kinda of a mess) and there was a time that we had a big fight, where I was openning up to her and said because of trauma with my parents I had a problem trusting people and she asked, oh so you dont trsut me? I said i did but not 100% then she flipped on me, like she became cold and distance towards me and I kept apologizing for hurting her feelings and we only got past that because we had sex, we never actually talked about this and its been fucking with me ever since and I talked about this past couple of days ago and she almost didnt care saying she didnt know what to do about it but i was only expressing how I felt, but what really fucked me up, is these last few days she was busy with something and told me she would call me later, she took quite sometime like 3 hours so i decided to go play somethin, she called me and I was in the middle of the match I kept playing and trying to pay attention to her she asked me several times to pay attention to her- and yes I messed up I think I should have gotten out of the game but she hanged up shortly after I got out of the game saying she had trauma when someone didnt pay attention to her... so i felt like i needed to pay attention to her traumas whilst she doesnt do the same... I dont know if im overreacting or if im only being dramatic so I wanted opinion from the people outside and sorry again if this makes no sense And i didnt write the full story so i guess anyone interested I can try and make a summary of it or ion
