As to your question, you can't be refused entry to a house that you own, unless she has a court order preventing you from coming to the property. She would only obtain one of these if there was domestic abuse - which is not something you have raised - so I cannot see a reason why you can't go home.
If she refuses to buy you out, and you both want to move on, then you can apply to court to force a sale.
If you decide to leave her in the house until the kids are all adults, then you can chose to do this, but you would not be expected to contribute towards the mortgage/ bills if you are effectively excluded from the property.
You are not married, from what I can tell, so there's no automatic right for her to keep the property. Your children do need a roof over their heads, but provided there is enough equity in the property to make this workable (if it was sold for example you would both have money towards a deposit for a new house) then she does not have a case.
If she is the main carer for the children, you would have to pay child maintenance each month, which his assessed on the basis of the amount of time you have them with you, but this would be your only financial commitment going forward as you are not expected to pay for her to be housed (subject to the above point about making sure there is a roof over your children's heads).
I hope that this assists? Can I clarify anything further for you?
