My Dad and step mum have been married for coming up 30 years. Step mum was OW. My Dad used to take me to meet her when i was in primary school, he was still with my mum and would tell me to keep it a secret.
It must've all came out at some point and he left my mum and set up with SM.
Over the years there have been various things that have made me suspicious he's not been faithful to my SM. There are (horrible) stories I've been told about what he got up to with other women when he was with my mum.
He doesn't have, and never has had, any male friends. It's always been new women friends. SM only has my dad's friends. Never any of her own so has always been these women friends.
I met his latest female friend lately and I'm sure he's having an affair with her. He recently went abroad with her for a long weekend. I know this sounds ridiculous as I write it. It's the same MO every few years with a new woman.
I feel like I should do something?? Does my step mum know and turn a blind eye? Or is she really that fucking stupid?
I really don't want to deal with the fall out if its true. Ffs he's approaching 70 now. Its the whole hiding in plain sight. I've spoken to my siblings about it but they don't want involved.
Thinking about what I've written I should keep well out but I'm disgusted by it. I tried to "catch" him out the other night for the first time and I pretty much did but that's why I'm thinking about it so much more.
It was so bloody obvious and embarrassing the way he was going on with her.
What should I do??
