Just spilt with my partner of a couple of years at Christmas.
She has a 15 year old daughter who was a pain in the ass but manageable.
However she also had a drug taking a$$ hole of a 19 year old son who appeared at the house we had together a month after my partner moved in.
3 drug deals down the side of my house, steeling from me, getting sacked from jobs I had got him later it all went off the rails.
My issue was my partner who would not put common agreed behaviour controls around her own kids in which we all had a view of.
When she could not do that it was good night Vienna.
It was not about the kids it was about me and her, all a bit painful and raw but sadly inevitable, has it put me off no, has it made me suspicions yes.
