Hi David,
I'm an old maid, maybe soon to be spinster...lol!!! I think we all have those feelings, especially when we want to be the ones finding are life companion. Although I have to say out of all my friends that are already marriedm half are divorced, the remaining are somewhat unhappy in their marraiges. I have two friends that have been happily married, one of which lost her husband.
Many people marry for the sake of it's the next "logical" step, only to learn a little further along the road they weren't suited. I rather wait forever to marry someone I know meets my needs-moral character, values, etc..
Hang on, you will find someone, and when you do it will be lasting.
