Am I a bit odd not wanting to socialise? Or is my life not that fulfilling?

[Nursemammato3]

I'm 44 and I'm a single parent to 3 dcs.
I have been on my own (divorced) 12 years. Dated someone for 18 months in between. I never wanted to do much with him. I don't really want to do much with anyone apart from my dcs.
My job is quite heavy and I'm tired when I get home. I never plan to meet friends. Always turn down work nights out. I'm not on any social media. I don't want to date. I don't even miss sex.
I listen to women at work talking about meals out, charity events, dates, weekends away, classes they attend.
I am so boring!

I retired during the worst of covid restrictions. I lost my mojo for much socialising, but now do so around once a week with a friend. Usually we go to quiet areas with lots of nature as both live in a big city.

Also do lunch at quieter times. Boring, maybe, but much less stressful for me than full on entertaining or joining clubs would be!

A busy job and children - if you are an introverted type with a health condition as well - that sounds plenty to be going on with.

I myself am older than you OP, son grown up. I am pretty reclusive and I really like it. Also, most people are not interested in my interests (books, art), so there friendships tend to end up being a bit one-sided (I get them, but they don't get me!). Also alot of people are drama-llamas ...

HOWEVER, I have joined a MeetUp group and do the occasional activity with them at the moment. Am finding the socialising fine because its in a group setting and no commitments or demands so its actually fairly relaxing :). That said, there was a fall out within the group which seems to have impacted things. People, eh?

So, I think joining something where you can be social but no pressure and do occasional activity you enjoy, might be good. But if its not your thing, I see no issue with enjoying life in your current order of priorities. These may also change once your children are even older or leave home too.
