I don't believe love is hard to find. I think it's challenging if you're looking for a needle in a haystack and expecting to find that person very soon. Marriage is no longer the goal for many men under 40. The climate is changing and the shift didn't happen on our end. And the child-free population is growing. Many people don't want children. If you desire either you're working with smaller options.
Don't forget, the unchurched numbers are rising steadily. Many left and never went back. Some gave up the faith, pursued a different path, or call themselves spiritual. There are more Christian women looking for husbands than the reverse. It's a numbers game for some.
Some of this is related to the woman as well. It depends on your presentation and what you're seeking from the other person. I have never spoken of love or anything along those lines in my profile. However, I do mention character and the qualities I know are most compatible with my own. And I look for fruit in the other person.
You're focusing on love in your question but I think that takes time. Too much emotion can be a turnoff for the opposite sex. I think it's more important to look for a complement and allow things to go from there. Eagerness can be a detriment depending on the other person. It communicates neediness to some.
Many Christian women will have to confront the reality of relocating or addressing their must-have list if they want to settle down. I don't think that's going to change.
I don't have problems meeting secular men at all. Things are different on this side.
