He wants to move back after affair!

[Alc1411]

Please help, i am at a loss. I have just gone through breastcancer treatment. I was diagnosed in Feb and am now finished my treatment. Halway through my DH told me he didnt 'fancy me' anymore and wanted out of our marriage.
After 3 months of dealing with this, and his denial there was anyone else involved, it comes to light he had started an affair in January.
Needless to say i asked him to leave, this was on Thursday, now he says he is entitled to stay in the family home and is coming back!
I am just at a loss, i have a 17 &13 yr old who are completely devastated by his behaviour, and the thought that he thinks he can just come back and live here, until we sell the house....which i have not agreed to...is beyond me. Hasnt he hurt us enough.
I really dont know what to do, has anyone1 got any advice

With changing locks, what Darkly said is what the police advised me, it is not a criminal matter but a civil one.

Do what is right for you and your children. Living seperate lives in the same house is not easy on anyone

Wow, sorry lots of useful...and not so...advice, but thank you for the incredible support.
To update.
Apparently when he left it was only 'tempoary', and despite my best efforts at being reasonabke for the children, he has insisted on coming back until we reach a financial resolution.
He is not coming back to me...nor would i ever let him after what he has done.
S is very angry and doesnt want anything to do with him, at 16 fully understands what is F is, and DD at 13, is upset but doesnt want to loose him.
I will not agree to put the house on the market, as at this time it is the only thing i have control over, and its what he wants, so he can get his money and move on. I will wait him out, because as awful as it is....he is living in his bedroom, while i have the rest of the house, and his new gf will be putting pressure on him to leave, i dont think he will last long.
I am grey rocking...i do believe he is a narcassist...he has all the traits.
I will move, with my dc, maybe next year, but only after he thinks hes stuck with me in the house until my dd is 18.
I am seeing my solicitor today, and will get his advice, but i am trying very hard to make this as easy on the kids as possible.

Thanks for all the support. X❤😊

God this is awful for the children. What a dick he is.

It's great that you are so decisive. I think you need to let school know. Your DS is about to go into A levels and this kind of stress with his dad bullying you to try and get you to move house so he can desert his children, is the kind of thing that can get an able child to drop a few grades if not carefully managed.

Your ex needs to agree that he will not put his willy's desires before the needs of his children at this crucial time in their lives and that all decisions made are with their welfare first and foremost.

You sound really strong and with your head on straight. I hope it works out.

PS: I'm with @prawnsword on this one. Maybe not for your situation specifically but I do think us women are so scared of rocking the boat and as a result we are getting trampled over by these twats.

Forced to live in a house with someone who has cheated, abused or abandoned you is just another torture thought up for women.

I agree with Turtle. Make his life as uncomfortable as possible, And ensure he keeps paying a full share of all household bills. Just because his behaviour has him sectioned off in the spare room doesn't mean he stops paying his way for his children to continue their normal lifestyle.

Why is he back? Does the new woman not want him 24/7?

Well, if he moves back in (bastard), you do not do ANYTHING for him. No cooking, no laundry. Do not include his food in your family shop - just act as though it’s you and your DC. Act as if he’s not there.

Absolutely and tell him you don't fancy him anymore either!!!

@Alc1411 - if you are planning on moving at all, I'd go sooner rather than later while he still thinks you are doing it for his sake. If he gets any scent that you want to move, he'll block you and delay. You don't want mind games while your son is doing A levels..

Do nothing for him.
Apply to family court for an occupation order.
Get that cheeky fucker out, lovely.
