Your daughter is fortunate that you have turned a hurt into a positive thing for her. Perhaps some time when it seems right you can discuss it with your mother in a way that could minimize the possibility that it would hurt her, maybe just expressing how you feel without putting any blame or judgement into it, and see how she responds. You may be surprised, or she may not respond well, but you are not responsible for her feelings, that is her choice. Whatever you do my prayers are with you. It's good that you're sharing your experience, whether you are able to talk to your mom or not, you don't have to carry the pain alone when you can share it. I'm lucky to have a good relationship with my mom, it wasn't always the case. It was about me and my old resentments surrounding my parents divorce when I was 8 yrs. old. On the surface I was a loving son mostly, but deep inside I harbored resentment and pain. When I got into the 12 Steps of AA I was able to let go, forgive and be forgiven. I was 35 when that happened, but it's better late than never!
