My DH has always been one for going out at wkends
About a year after we got married I had to have major surgery. As I was discharged a day earlier than expected someone else had to pick me up as he was working. When he eventually got home he announced he'd made plans to go out clubbing and had told a mate he could stay over. I felt too I'll and shocked to argue but have never forgotten it.
When DS was born 3 years ago he carried on as normal and expected me to be out with him and friends. TBH he would spend most of the time we were out harmlessly flirting as he called it! DS was forever staying at his grandparents at wkends. I was really missing being with him so told DH I wouldn't be out nearly as often. He is still out every wkend, sometimes staying out all night.
To top it all I have PIL on my back as they are missing having my DS staying over so often and want it to become a regular thing again.........
