I know so many woman in this same situation (I live in Cape Town)
There are several issues. The first is possibly that the guys who commit get taken early.(this is me) The second is that the cost of weddings and kids are a major worry for the guys who are on the fence about marriage etc. Then there are a lot of guys who are not married for a good reason.
So if you are looking to find someone you would be happy with there are a few options:
1: The shy/loner guys - So many nice guys who are hiding because they struggle to talk to girls.
2: Divorced/bereaved - Each have their own risks but they were willing to commit at one stage.
3: International
4: Dammaged goods/guys with issues - Only if you like a project.
So how do you meed people. IF you use things like Tinder it will help you get into the game but you probably wont find a husband. Its good for practice.
My MIL just found something that seems to be working well
https://www.meetup.com/. Its area specific and for anyone who wants to meet like minded people, so there are hiking groups and others that go dancing. Its not just for singles so its less of a meat market than tinder.
Whatever you do - don't bother with church.
