I can see that. For me, I had the "loneliness in a crowd" effect. It was only when I stopped expecting people like my ex and G to be supportive and kind, that I looked up and saw this big world in front of me. Now, I have no shortage of people who respond right away to invitations, or invite me to do things. I like my alone time, but it's very nice to know people I enjoy, and who appreciate my "me-ness" are there to join in our mutual game of life once in a while.
So, from my prior experience of having people I really cared about and loved not being able to reciprocate because of whatever was going on with them, I was able to just let S go. It was so disappointing, because I still believe we could be good friends. But I'm not going to focus on what I don't have. I can just tell myself that clearly he needs help and focus on people who enjoy me in return. I'm mostly joking here. As do I, S sees that we have work to do and we're each trying. Naturally, I think I'm winning, but I can be competitive that way. Anyone who truly tries earns my respect.
I do think about S a lot. He's really highlighted areas that I need to work on. Old Me would have tried to change his mind. New Me only wants to be friends if he wants that too.
Life lesson; under belt.
