hello shiny, i never post on the forums, but i have been following your situation since the beginning and i have read all the posts.
i am in a very very similiar situation to you - including the marriage of convenience (i didn't realise why he was so keen to get married at the time....), the seeming infidelities, meanness with money, hanging out with dodgy characters, unrealistic dreams (wannabe donald trump) and fantasies of becoming a millionaire, even right down to the weird staring thing.
when i found out my husband had been sleeping around with other women and giving them money while we were trying for a baby
and after i miscarried, i lost it and started a physical fight in front of my 4 year old child that ended with me slashing my arm in a glass door. i am the most passive non-aggressive person you could imagine and my daughter was absolutely terrified. he too had been verbally abusive, dismissive towards me over the years amongst many many other things, but this was the last straw for me as i realised i had hit rock bottom.
i accepted that he had never loved me, probably despised me for reasons i will never understand and that i had never had a marriage, and would never have a loving marriage. this was about 2 years ago and i posted here for advice around that time.
the ladies here were wonderful and gave me a lot of the same advice you've been given here. i got my plan together, adopted from within my family so that my daughter would have a sibling and started looking to get out. we never had a conversation about anything, because i had tried over the years, writing letters, getting a family member to act as an intermediary, openly offered him the chance to say he did not want to be married but had achieved nothing.
so i moved into the spare bedroom, expecting that at some point he would leave me (i decided i wasn't going anywhere). he hasn't left, though he still might later. i work part time and i do find it a struggle to cover all the bills and things for the kids, but he pays the mortgage and i don't ask him for money unless i'm really desperate.
my husband may resent me, but he adores the children, even the adopted one. i had a hellish childhood - i don't know my father, my mother was verbally and physically abusive towards me, though not my sibling. and she was a true "imma do me" type - moving her abusive boyfriends into the house with us children, leaving us with her boyfriends to go on holiday etc etc.
i am very determined to do the best for my kids and fear my husband would abandon them if i insisted we separate. also, i would never bring another man around my kids and knowing what my husband is like, would not tolerate him bringing any of his girlfriends around them. i stay to protect their interests. he may leave, but home is peaceful for the kids for now, something i never experienced, there's no arguing or shouting. we're both civil and polite to each other and he is very involved in the kids daily routine, schooling, teaching them to ride bikes etc. i stay focused on the kids, running the house and my job. i'm no martyr, but i am willing to sacrifice these years so that they can have a better start than i did.
i was abused by 2 of my mother's boyfriends, and now have had almost 9 years of misery with this man - though i desperately long for a loving relationship with a man, i accept that it will not happen for me. my children did not ask to be born and adopted and unless home life were to become unbearable, i don't want any disruption for them at this time. besides, he may leave me at any time anyway.....
previous posters have advised you that you need to become emotionally and financially independent of your husband and this is what i have had to do also. i don't feel sorry for myself, i should have seen all the red flags at the beginning etc. also, i have much to be thankful for in life and i try to focus on what i do have. but i am very low a lot of the time, i'm looking into getting counselling - eat too much etc. some mistakes in life are more difficult to reticify than others.
1) like many other posters i think your husband is cheating. the "you don't work thing" is a bit of a smokescreen - raising 4 children is no joke and i'm not sure why some posters are trying to imply that it is. i've always worked and i know that there is absolutely nothing wrong with a woman staying home to raise her children. i thought the youngest had only just started kindergarten..... please please please get yourself tested. i have had several HIV tests myself and i'm still going for another one just to be sure. the numbers of black women being infected with HIV by their men is frightening. and please don't sleep with him anymore. he's basically said he doesn't want you anyway.........
2) i understand not wanting to move to your mother's - i think you mentioned shame or so. also, it would really upset the kids and you don't want them upset at school etc. i think you should concentrate on trying to find a job.i don't think you and your 4 children need to leave the home. your husband has mentioned getting a room and paying the mortgage - he may not mean it, i suppose.....
i'll stop there as i didn't want the post to be so long. you seem to be reading all the responses, so i just wanted to wish you the very best and to give you a difference perspective on your situation. also, please keep up updated on how things go so we don't worry what has happened.
take care of yourself and your children, i'll keep you in prayers
