Not spoken to grandma for nearly 5 years. Leading up to the fall out I visited her every week with my child who bonded with her. Cutting a long story short, I was getting married, my bridemaids (her grandchildren) caused problems (diva vibes) and didn't end up coming to my wedding let alone be bridesmaids. On the wedding day my grandma was miserable, making comments to guests and muttering stuff during speeches. She also stopped my mum enjoying the day because she wouldn't let her leave her side. I told grandma on the day to go home if she didn't want to be there. Her problem was the bridesmaids not being there but since that day I've never spoken to her. I've never forgiven her for it. My mum's asked me to go and visit my grandma because she doesn't think she has long left and I don't know what to do. I've always said I would only visit her if she reached out to me. I'm conflicted and don't know what is the right thing to do. Any advice would be appreciated.
