have posted about this prize tool before, so some of this may be familiar to some of you, apologies if so!
i can't tell either my friend or her DH what i think of him as it just won't be worth the inevitable fall out. i tried once but he made her life hell over it and stopped her seeing me, so i would like to have a massive bit of a vent on here if you don't mind :(
1, he picks on one of her DC. they have 2 DC and only one is his bio child (dc1 is from friends prev marriage) he bullies her., the other day she (dc1) started talking and he yelled at her to shut up. i wouldn't speak to a dog like how he spoke to her. he also refers to dc1 as "narcissistic"
just because she is a bit of a show off at times. she's 5 btw and i think thats a terrible way to describe a tiny little girl :(
2, he controls my friend financially. she is a SAHM as her youngest is only 3 months. ALL her money (ie child benefit, tax credits and maintenance for her eldest dc) goes into HIS bank. and if she needs / wants money she has to ask him. he will fritter away money needed for rent / bills etc on expensive gadgets and suchlike. they are in mountains of debt.
3, he doesn't work. HIS choice. he has had jobs but quits after a short while. he enjoys boasting about sitting at home and generally laughing down his nose at all us suckers who go to work. (not benefit bashing btw, i have been on benefits and have zero problem with benefit claimants but i do have a problem when people brag in this way)
4, he controls my friend emotionally too, he has caused her to be completely estranged from her mum and best friend (long story). he also tried to break up several of her other friendships as well by poisoning her mind against people. and if she ever goes out without him (which is very rarely) he constantly calls or texts her 
5, he does sod all with their DC, she does everything whilst also running around after him as well. and if she wants to go out without the DC he goes all funny over "babysitting" 
6, he is "friends" with dozens of young girls (teenagers, he is 31) that he is always flirting with on facebook. he also makes sleazy, dirty comments to me and her other friends. yet my friend has ONE male friend that its not worth her while seeing anymore as her H is so jealous of him. oh, and this male friend is GAY ffs.
he is a horrible, cocklodging, controlling, waster of a bastard and me and all her other friends have completely got his number and i think he fully knows it. but NONE of us can say anything to either of them because she is completely in his thrall and she would fall out with us out of some misguided "loyalty" to him as he would emotionally manipulate her into ditching us. which would mean not only would we lose her as a friend but she would be even more isolated.
i am sorry this is so long but i needed to get it out somehow. i just hate keeping my mouth shut about all this, it feels like by me not saying anything i am condoning his dreadful behaviour and treatment of her and the dc :(
