I'm so sorry to hear about your loss; I suppose you can understand what I'm going through then.
What lead to the issues between you guys?
Originally I think it was my choice in a particular boyfriend he hated but then we had an argument about something stupid I can't even remember and he stopped talking to me when I visited them. He had heart health issues later in life, a couple bypass surgeries, then Parkinson's and then more heart issues at the end. Granted I wasn't around a lot because I worked a lot of hours and had my own life but didn't try to make amends until a year or two before he passed but was still ill.
Sorry we got off topic here!
