Not knowing

I am black my husband is polish, we have 2 kids together. His family accepts me and other dont because of our mix race. Sometimes i feel like i dont want to be with him anymore because its not perfect like i wanted it to be. I want to leave him because i wont be accepte by family of his but is it normal for that, i should only care for him maybe. Sometimes I am just angry because i feel like he thinks maybe i am just exotic because in his country they hardly ever saw african americans ( poland) i feel like he doesnt love me as much as i do for him because he doesnt show the world that he chose me and he doent give a crap what anyone thinks.. I dont know i just feel like leaving because its not what i wanted..is that selfish?
