Dating in your 30s as a nerd

I (m,35) was just dumped 3 weeks ago by my gf after 2,5 years out of the blue. Inwas thinking about how im ever gonna date at my age again. I know this might Sound stupid but hear me out: Im quite shy with people i dont know, introvert and really "nerdy", i like things like Video games, pokemon cards, warhammer, anime. I also do other stuff like going to the gym, hanging out with friends etc.

The problem i see is, the most women my age wouldnt want someone with my interests or if, dont do any of them with me together. My last gf was really into almost everthing i did, and it was great.

Another thing, most woman in this age already have kids, which is a instant no from me. I dont want kids, and especially not kids from another dude. Been there, done that, never again.

I know about dating Apps, but thb i never got a relationship out of Apps, most of the time it was from mutual friends/accident. But my friend circle is not that big, and all people there are too young or already taken.

So how did you guys do dating as nerds in your 30s? Any advice, Tips or experiences?
