Online dating has been pretty useless for me too (and I even sign up for the paid subscriptions) but when I looked at my social circles or my own tendencies and saw there is not all that much to work with, I decided to give online dating another try. I might still start asking around about setups or maybe an opportunity will arise if more people I know in real life or social media are aware of how I feel or what i desire. I plan to continue with online dating even though the service I am on now has not yielded any dates, i might switch to another one.
Being vocal about wanting to date might just put a bug in the ears of people you know, even if they have no idea you want to date or might even try to discourage you. It may not seem like it, but some of those people you mentioned could be an unexpected source of a potential date sometime in the future. And even if it seems God is keeping single women you could date away from you, He knows your heart, desires, wishes so keep praying (even if that feels useless). God knows what we want, if it is right or what He wants for us and when to give it to us when the time is right but He always loves hearing it from you.
The resources I listed do not scratch the surface of what is available as far as Internet web sites/blogs, books, seminars, relationship coaches, etc. There is so much more in resources. Just a matter of some hard-nosed searching. Or maybe even talking to some older adults at church, maybe even of the pastors; just don't get discouraged if they actively try to advise to not search for a partner.
I've been told to stay single/not marry by plenty of people (and probably a few more will tell me) but I remain committed to taking action even if just praying and listening to God. And if in the end, I don't marry, at least it would because God did not want it for me instead of me not taking steps toward a goal, and I would know I gave it my all.
All of my advice is based on past or even current experiences in my life. when I was 29, I had not gone out on one date and probably did not care about it as much as you seem to now and I did not end up going out on dates until I was 31.. and sadly that is the last time I've gone out with someone. I am hoping with all of your scrutiny, that you will land dates and a relationship(s) a lot sooner than I did.
