Married less than a year finances on separation

[DeceivedAgain]

What is reasonable?

I just discovered my spouse has carried on a relationship behind my back the whole time. When we married they had debts and a small pension pot. I had a mortgage free house.

They don't work or contribute to household expenses and have liquidated their pension to use as spending money.

I can't work now due to SEN child so used up most of my savings to cover bills. Will they have a claim on my house or savings if I apply for legal separation?

I would prefer not to divorce for religious reasons.

That's an absolutely fair point and I didn't want to ignore it.

I apologise for not sharing my personal story more fully on this thread but ask you to take into account that people and circumstances can change dramatically.
