<human>: Reddit, I'm usually a lurker but I am incredibly confused on what to do.  My ex (we're both 27 and were together for 7 years) broke up with me 2 months ago, because she fell for someone else and they have since become a couple.  I was heartbroken, but did the whole "hit the gym, end contact, etc".

I haven't wanted to see her because I've made great progress (dating other girls, etc) , and haven't wanted to ruin that by seeing her and becoming an emotional wreck.

I found out today that her younger brother was killed in a car accident.  I spoke to her and offered my condolences through phone (first time in 2 months), and she informed me of the memorial time. Now, I'm afraid if I go to the memorial service, I will fall into the bf role, because you don't just shake off a 7 year relationship like that, especially when you see someone you cared about so hurt.

I have no idea what to do, do I try to take the high road and potentially completely mess up my recovery?  Do I avoid going and it becomes incredibly selfish?

Summarize the given text in a few sentences.
<bot>: Ex of 7 years broke up with me to be with someone else, and I cut contact with her so i don't fall in a spiraling depression.  Her brother just died.  What do I do?
