Do not listen to most of what she is saying. a non-mol and occupation order are not awarded simply because she wants them. There has to be good grounds for example domestic violence. But if she is trying to get them then she may fabricate or exaggerate things so make sure you do not put a single foot wrong or even raise your voice. She may try to start a fight in order to get you to retaliate, so simply walk away and say you''ll discuss it when she can talk rationally. DO NOT move out.
Welcome - glad you took the advice about coming here. Check back to the other forum.
To get the best advice you will need to give more detail. Respective ages and incomes, length of marriage and cohabitation, ages of children, assets, inc pensions and liabilities, value of house and outstanding mortgage. The knowledgeable wikis will also need to know whether that other house is genuinely hers or is just being ''loaned''.
If you propose to be the main carer you need to get child benefit transferred to you.
