<human>: Can you summarize the given text in a few sentences?

Hello everyone. Just like the title says. I dated this woman for 3.5 years. I ended it. We had no contact. She called me once about 4 months after the break up. Haven't heard from her since. I just found out through her cousin's FB post that her grandmother passed away. I was very close with her family and her grandmother. 

I want to say something, but should I? Nothing to try and win her back but just something along the lines of "I heard your grandma passed. Just wanted to offer my condolences to you and your family. I don't require a response. Just wanted to lend my support, not that you need it."
