@AllThatJazzZ
You have my deepest sympathies at your loss. You say you have no family yet you had a stepson and he had Daughter (+ hubby), 2 sons and a brand new granddaughter. Did you have no relations with them? Perhaps through tragedy a door may open?
@GtHawk Good catch! I realized it sounded contradictory and might require an explanation. Let me clear it up for you and the others.
Of my family of origin, my parents have both passed. My husband passed in '70 at 23. I met a man from Los Angeles a couple of years later and we married. He had 2 kids from his first marriage, and we were fortunate enough to get custody of them. Not because their mother was incapable or on any type of substance. She had a new baby with her 2nd husband, and the "kids" (my step-kids) actually wanted to come live with us. So we had the best of both worlds. We had custody of them, and got to send them to San Diego to their mom's every other weekend. I used to have guilt about looking forward to those weekends until all the finest moms I knew said they wished they had a place they send their kids every other weekend! Anyway, mine are the best step-kids in the world.
I moved back to Texas when we divorced. I didn't get to take the kids with me (for obvious reasons), but it wasn't for lack of wishing I could. I got the dog, though. The 1600 miles, various life events, ex's remarriage and then divorce -- these all played a part in keeping us mostly separate. We talked on the phone at times (remember those?), and stayed nominally in touch. I went out for my step-daughter's wedding in 88.
A few years ago, their daddy (my ex) passed. There was a memorial celebration of life at step-daughters house. She kindly invited me to come stay with them. I hadn't seen them in years. We got to pick up where we left off in some ways. My step-son and I sat in the living room and sang "Jesus Christ Superstar" until we were hoarse -- and without missing a lyric! I got to meet all my step-grandkids for the first time. Then it was time to go.
So once again we have the separation of 1600 miles. And very significantly, their mother is still alive and still in San Diego. So now we text and keep up more than be did before smart phones. I'd love for them to move to Texas, but they're native Los Angelenos (daughter now living in Ventura and son lived in Santa Clarita). I can pretty much guarantee that I won't be leaving Texas again. So it will just continue on this way.
Re my family of origin... no siblings (therefore no nieces or nephews), no kids (therefore no grandkids), no aunts or uncles still alive. I do have cousins scattered around the US. We all grew up in the same small town in Texas. I've come full circle, but they're scattered hither, thither and yon. My immediate family for the last few decades has been of the 4-paws variety.
Aren't you glad you asked?!

TMI? I think I just needed to get it written down. Turns out, it was a kinda therapeutic.
It's funny how life throws a curve here and there and your life doesn't even come close to resembling what you thought it would when you first launched out on your own.
