He tells0 me I am not the right women for him and that he hates me. He says to me if I get pregnant he will abort the baby. He comes home late everyday and does not eat at home. I dnt no whr to go I hav no place to stay and he keeps on tellin me to move out. And I mus make the first move. My parents disowned me and my mother hates me. I had a very difficult and painful childhood. And I got married at 16 jus to get out frm home coz my mother use to abuse me. She burnt me and broke my eardrum. I made a lot of sabr till today. Recently my husban sold his blackberry phone jus all of a sudden and is usin a old nokia phone. I am gettin suspious. As his pro pic is still on my bb phone.

And she saw that 3women on face book is conected to my hustban. Help me he lies and hides a lot from me. How do I catch him out. How do I go to check on facebook if he is really cheatin on me

Slms dear sister.
I'm truly sorry 4 all that u r going thru, may Allah ease your burden and grant u the strength to get thru this, Ameen.
My advice is for u to get freedom thru financial independance firstly, so get a job or start selling something 4rm home so that u have your own income. then when u r ready to leave your abusive husband, u have a leg to stand on urself so that u don't have to worry abt who is going to be there 4 u.
The fact that he's abusive should be enough reason 4 u to leave the situation with your kids. Why should it matter if further than that, he's also cheating on u?
Take care and please get yourself and your children out of that abusive situation.
