I have another kashya. The OP only says “Baruch Hashem” about those who find their bashert very quickly and start a family. If anything, though, someone who waited and were then able to start a family would feel more grateful, and shout “Baruch Hashem” with every fiber of their being!
So, my sweetest friends, I will share with you that I think the OP is saying something deep – very, very deep.
We know in Chassidus it says that ugly people have more yiras shomayim. Of course the lamed vov tzaddikim, who know the secret of being real, see people with yiras shomayim as exquisitely beautiful, but as for the rest of us, who ate a big breakfast in the Rennaisance (or at least have a big breakfast waiting for us), they’re hideous.
So I think what the holy OP is telling us is that people who lack yiras shomayim, who tend to get married right away, can still have a good marriage if they learn to always say Baruch Hashem.
And the chiddush of the seifa (give me harmony, hold on the last note) is that even the holy, holy people with such awesome yiras shomayim that it takes them a bit longer to get married, also need tips from the OP to keep their marriage strong.
