I'm hoping for a bit of insight and advice, or at the very least maybe just typing it out will help clear my head. My parents separated when I was in my early twenties (about 8 years ago) when my Mum left my Dad for a man with whom she'd been having an affair (they split up soon afterwards though). I found out that she'd cheated on my Dad previously as well, including when he was recovering from serious illness. For the record, my Dad is lovely and I think my Mum just got bored, he wasn't abusive or anything. She has also always had low self confidence, and I think she just found the attention from other men too flattering to ignore.
The split was amicable and they are still close friends. In come ways things haven't changed much, they just aren't a couple anymore, and live separately. My Mum has always been one for "keeping up appearances" and you would never expect her to be the type to cheat on her husband. She broke my Dad's heart, and obviously upset his family, but feels persecuted when they treat her differently because of her actions. I think she sonehow feels as if these are things that have happened to her, rather than things she has done, and she feels aggrieved that they have consequences.
The latest development is that she is now having an affair with a married man. Without wanting to sound naiive, I find adutery abhorrent, and feel angry and disappointed that she seems to have no problem with cheating, either on her own partner or on someone else's IYSWIM. I suppose I'm also slightly worried about what could happen if this man's wife finds out about the affair.
I find it hard to reconcile my anger at the way she treated my Dad with the fact that she is still my Mum. Outwardly she hasn't changed. She is also a doting Granny to my baby daughter. Thinking about how she has behaved and is behaving makes me feel incredibly angry. She can also be very critical of other people's behavious, and sometimes I want to scream at her for being such a hypocrite.
This is probably hideously long and rambling, so thanks for reading if you've made it this far. I suppose my question is: what can I do to get over the way I feel about all this?
