Husband been having an affair but not admitted it

[RalphieJ]

My husband walked out over a month ago, saying we had grown apart etc.
ive now discovered he’s been having an affair and is staying with the other woman.

currently he stays at our house when he has our child, the house is jointly owned.

have I got any rights to ask him not to come back here? I find it hugely disrespectful, he’s still lying to be and clearly can’t be trusted
i have been more than amicable with him

No.

See a solicitor and serve him with divorce papers - that will send a clear message it’s over for him.

no unfortunately

get moving on the divorce

None - he jointly owns the house.

Sorry you are going through this. It is totally understandable that you have completely lost trust with your ex. Unfortunately this saying there is no one else and lying about it appears to be quite common.

As others have said, best push on with divorce and figuring out contact arrangements in the best interests of your child.

No I'm afraid you don't. Regardless of his behaviour and his lies , he is half owner of your house and unfortunately for you can come and go as he pleases.
The law doesn't get involved in fault .
