I've been in a somewhat similar situation, although back in the day I was playing with several bands on a pretty much full-time basis.
Then married life, kids, and work all got in the way and it's only a year or so back (ie 25 years after my hey-day) that I've had the time and freedom to try and get back to playing out.
It's not been easy.
Of the guys and gals I used to play with, there's only maybe 3 still play anything at all.
Of them, 1 is in upstate New York, the other 2 were later to kids than me and still have a lot of responsibilities there, so hardly any time.
I joined some FaceBook groups, set up a couple of jam sessions, have been to a few open mic nights and have met a few new people.
One problem is there's a big age gap so finding common ground on tunes to play can be an issue - I admit I'm still living in the past to some degree in my music likes and in what I'm interested in playing.
I also find myself a lot more intolerant of a lot of the stuff you'll read about in band horror stories...lateness, lack of preparation, kids these days

...
Another problem is that I'm nowhere near as good as I was - I never learned to read music, and my memory's not what it used to be.
Also hand and back problems make it difficult for me to play for too long.
That all said, I have had some very positive experiences recently, and while I haven't got that fully functioning, gig-ready Commitments/Blues Brothers Soul Revue just yet, I am slowly getting there.
You just have to keep plugging away, make what new contacts you can, be prepared to compromise a bit...
But keep in mind the whole thing's supposed to be fun !
