Drastically cutting monthly money...please help!

[Areallmencheats]

My husband of 22 years unexpectedly left me last year, moved straight in with OW and has been paying my monthly bills of £1500 ever since.

I've left him and her to get on with their lives as I've no interest in a man who can desert his wife and sons (19 and 22) overnight having led a double life for months.

I've just received a message saying that now both is my sons have moved away he's going to reduce his contribution to £750 per month and that he wants me to put all the bills in my name.

He earns £4200 a month after tax.
I work full time, £8 an hour.

Surely I'm entitled to more than £750??? I can't survive on that. It doesn't even cover my rent of £850 let alone bills.

Please can anyone give me any advice on what I can reasonably expect him to give me every month.
Thank you.

I know every case is different but is there a general guide to what the non working spouse caring for dcs would be awarded? I don't say given as I dislike how it's always deemed as what the man would give the woman. It's either shared assets or it isn't.

@Babyplaymat yes you may well be right but if he has assets the op was not aware of...he may not mention them in the financial disclosure as he may have sold them off / transferred into someone else's name.
OP I don't mean to panic you but just get onto the solicitor. I was in a similar position and in hindsight I really messed up because I gave my EH plenty of time to sort his finances out before we got solicitors involved.

I would suggest file for divorce and start a new life. Why would he continue to fund you when he doesn't live with you ?

I know very little about the legalities of any of this, but am amazed by how much he’s been handing over each month given how old your children are.

OP it's very hard for you and I really sympathise with the position in which you find yourself. In addition to all the financial worry you have the emotional pain and betrayal to contend with. I'm a dreadful procrastinator so do understand but if you can go through all your monthly outgoings and make a note of the provider, you should be able to identify savings - these were mine: changed mortgage term; bought cheap second hand mobile and moved to £10 sim only contract; switched energy provider; cancelled gym membership; cancelled Sky; got single person discount on council tax. I also saved a fortune not having to buy food for greedy ex or pay for his holidays. Good luck OP it will get better
