Problem with rls

i tend to been feeling like my gf dosent love me & she only with me to use me for things i provide. At one point i never felt like this now i do, we been together 6 going on 7 months saturday & i just don’t know what to do i made alot of mistakes not once cheated but i tend to not see my actions & always provoke her. I also tend to use aggression/abuse to solve my anger problems but i feel terrible & want that to change. it’s 1 reason i use violence due to what i went through growing up, its no excuse but i never hit a female i was with in my past just her i been doing this for 4 months at most & i really try my hardest to stop but its like i have a toxic leak in me
