Hello all.

Ive been with my partner for 3 years now but our relationships is dead in my eyes. She has cheated on me, punched me clawed my eyes and smashed my belongings when i try and leave she takes an overdose or self harms. I feel ashamed and weak by saying im afraid of my partner im 6,2 and 17 stone so not small at all and she is 5, 2 and tiny yet im terrified of her i have never raised a fist to her its not how i was brought up (though i have enjoyed the thought many a time) I have no life with her anymore she tells me what to do all the time by this i mean demands i make her a cup of tea or demands i pass her the remoted even when im in the other room. i bust my balls at work then i come home and do all and i mean ALL the housework and look after our son. Then when the place is a mess she tells every1 she had cleaned and i messed it up im so sick of her i cant think of anything i like about her anymore everyone tells me to leave her but its not that simple. 1 if i did no way would i leave our son here with her due to her mental health isssues but im afraid of taking custody as i have recived threats from her family and if she does manage to do some harm to herself i dont want it on me. She demands i quit smoking yet cant see the reason i smoke is because of her when she is not here i dont smoke at all if she is here ive been kwon to go through 50-60 a day. PLEASE SOME HELP ME
