I think writing to her mother is a wonderful idea, honestly. You have nothing to lose by doing so. I’ve always felt strongly about expressing my gratitude to the people I love; you never know…they may be here one day and gone the next. It’s slightly pessimistic to view it that way but it conditions you to not take anyone for granted.

Anyway, you have a great opportunity to write to her and I would take advantage of it. I think she’ll be extremely happy to hear from you and it shows that you are a mature and thoughtful being for wishing happiness and good health upon the family. There’s no need to address the breakup or the guilt you feel–deep down they know you mean well.

You will feel a great weight lifted off of your chest once you do this, I can assure you. Unspoken words have a way of gnawing at us until we voice them. And then suddenly…we feel light again. We feel rejuvenated and refreshed. I say go for it!

Best of luck 🙂
