I'm devastated and don't know what to do
I've seen a Daddy-type guy (~20 years older than me) casually for almost three years now. I know he has a bigger network of hookups, but he largely kept me out of it, and we'd just meet 1x1. Each time it was always great hanging out and talking, and he was very much a casual father figure kind of person in my life.
Lately we haven't seen each other for a few months because of random health issues, travel, etc. We were talking about finally meeting up again this weekend, but I didn't hear back from him since Thursday.
I just found out this morning Sunday from our one mutual friend that he died suddenly on Friday night.
I have no other contact with any other people he knows, anyone in his family... it was very much a casual, side relationship for the entire time. But we were pretty close, and I really enjoyed his company, along with the intimate sex we had.
But now I don't know what to do... I have no other lines of contact, my friend has no other information, and I don't know where I would even get an update. I could reach out to his brother, but an email to a family member given this relationship would be very unexpected.
What the heck do I do besides sit here bawling my eyes out on the couch?
