Thanks for telling me I am psychotic. That is so civil of you. OP is ready to purchase the house and OP should not take the financial risk of joint ownership with someone who is not a spouse.

There is no rush to marriage because the decision to marry has already been made. Having a marriage service performed at the county office protects OP and source legally, and they can still have the planned cultural wedding service and reception.

Blocked for your lack of civility
