My brother did this to me
It was over 20 years ago, but I still hold this against my brother and mother.
I had met my first love and couldn't have been happier. She flaimef to love me back. Long story short, after a couple of years my brother and her were seeing each other behind my back, sometimes at my mothers house, while my mother certainly didn't approve, she did cover for him (I hope to keep me from getting hurt). It went on for a long time until my friends got together with me and let me know.
I'm not sure which part of it bothers me the most... me working all over the country and paying rent while my jobless brother was living at my house on my bill and screwing my gf or the fact that my mother was hiding it all from me. Either way, I've never talked to my brother since and have only spoken to my mother when relatives have died. I even missed my grandmothers funeral because I knew they would be there. My ex gf was killed a few years later by an angry wife who caught her with her man.
My sister also disowned them for abuse by my brother that our mother turned a blind eye to.
Am I holding onto this for too long? Should I let it go and forgive them? Or am I better off without two sociopaths in my life?
