The way most people find love now seems to be on Internet dating sites.
It can be lets say 'interesting' and takes patience and time to find a suitable mate.
You might have to kiss a few frogs before you find prince charming.

One thing more thing, you say you are very capable as your ex was a useless lump. Same as me! I actually found I was more capable than most males I met.
I can put up a shelf, deal with spiders etc. I thought l was being impressive but men IMO were secretly irritated by it. Its not PC to say but men rather like it if they can 'rescue' you from spiders and put a shelf up better than yourself.

30 is not remotely old!

From you description of yourself you shouldn't find it too hard.
