Trapped

Hi ladies.

I'm in a relationship, (new one) he makes comments about other girls. Says "fuck" to half naked woman. I'm 4'11 and abit over weight. When we argue he gets my aunt involed. He accuses me of cheating. When I've never done it in my life, when he doesnt get his own way he threatens to kill himself, he contacts my aunt which ive got threatened by her because of him. I feel trapped as she likes him and will stick up for him and go nuts at me?
