Hi, my fiancee and I have been together nearly 10 years and when we got together she was a bit of a party animal but did calm down a bit but the last few months she has gone back to her old ways and every few weeks she goes out and doesn't come back for days, she also makes no contact during this time not even answering texts.Twice in the last month she has gone out on the Friday night and not come home till Sunday night, at the moment she went out on Saturday morning and is still not back and it's Monday morning.I am getting really sick of this now and don't know what to do as we just bought a house together last year.
