I am a stepmum myself, and try to do my best(facing some issues but another story stor)
I am also a step child. I became a step child when I was 23 we have never lived together as I had already moved out by then my mum said she was happy so all is fine.
I wouldn’t say I’ve ever really got on with my mum’s husband, but I have always tried to be civil, as like, I said she’s happy and I don’t have to live with him so not my problem
when I moved further away to live with my now husband, she would come and visit once a month. No problem she would stay for dinner and we would have a good catch up. Husband never came as he was always working or with his own kids.
Since I had my son 3 now my mum has tried to come once every two weeks so she can see him but over the last year or so she’s not been able to visit as her husband has told her he has plans the morning. She plans to visit us or when she gets here, he will ring with some sort of emergency where she has to travel back again, this is a 90 minute journey each way.
Personally, I think it’s old as she always seems so upset that she has to leave. My husband thinks it’s jealousy, but I really don’t know how could a grown adult be jealous of a toddler?
