Name changed but am a regular poster.
I have a friend (A) who I've been mates with for about 6 years- our kids went to school together but aren't friends and it's a close friendship; I had a key role in her wedding last year, we see each other regularly etc.
Last year she fell pregnant by a married man who promptly left his wife and son who is now 5. It transpired the marriage had been unhappy and they divorced quickly so I got over my self-righteousness and figured it was just an unconventional start to their otherwise seemingly happy relationship.
They married last September and she's pregnant again. Since then she has turned into an evil stepmother. Her husband gets paid overtime in cash which is declared and she still complains constantly about the money they pay towards maintenance a pitiful £45 a week. She makes every effort to sabotage her now husband's relationship with his son and contact is now down to once a month. She's erased any sign that the son even exists whilst her son (from a previous relationship) has started to call new husband 'Dad'.
I'm really struggling to maintain a friendship with her after having seen and heard her be so cruel to a child. DH says it's none of my business and shouldn't affect our friendship but when she says things to me like "I'll make him miserable this weekend so he doesn't want to come next time" I just want to take him back to his mum. I challenge her every time and she just laughs and says she doesn't care if she sounds like a bitch she does. This weekend she is gleeful because he's not well so she, and therefore her husband, won't have to see the son until the end of June. Her husband used to push back but she'd kick up such a fuss he just goes with it now.
Others in our friend group seem to have some sympathy for her but I have absolutely none and I can't bite my tongue anymore so considering just cutting contact. I'm not the unreasonable one here am I!?
