Do you have an odd story about living with your mate as an unmarried couple?
Although I had visited her parents many time over our then 10 years together(9 of them living together) we always opted for the hour and a half drive back home. If her parents visited us they also drove back. If her Mom took the bus up she stayed with us even spent long weekends and up to a week a couple of times.
Last year a late evening storm made travel a problem and my gf suggested we stay over. Her old room was unused but still furnished (younger sister had it before going off to college) and she figured we'd bunk in there.
Much to my surprise her Mother brought a set of bedclothes to the living room and said " You can sleep on the couch and my daughter can use her sisters room."
GF & I though Mom was joking. We were shocked when it became apparent she was not joking one bit.
Her Dad said until you are married when you stay under my roof you sleep in separate rooms.
GF looked at him and said "We'll leave now if that is the way you think and feel about our ten year relationship". We drove the couple miles to a motel and made the trip home the next evening. GF effectively cut herself off from conversation with them and will not even talk to me about fixing it.
FWIW we were both 31 at the time. If GF wanted to get married I'd say yes but she made it clear that she does not even want me to ask. Marriage was never part of our life plan together and I'm sure we'll go to our graves in unwedded bliss.
BTW after a couple of years the rift healed a bit but we avoid talking about the subject and our visits to her hometown revolve around day trips only. My parents have died and Xmas& Thanksgiving is at our house and her parents 'have other plans for the holidays but thank you for the invitation'.
