Countless cradle Catholics have strayed from the faith as well. Sometimes for a relatively short time (months, years), but sometimes forever. I've read quite a few honest accounts of just such behavior from cradle Catholics in my time on CM. I figure you know this too, but I'm just pointing it out anyway. :)
In the end, this is a risk we take with anyone. Not just converts, but anyone. Two cradle Catholics could marry, but one could eventually lose their faith. The best we can do is find an upstanding person of great character.
I want to say converts are the best Catholics at least what I have experienced in my family. I have 4 converted SILs and BILs, and they have been converts for maybe 20+ years. They make great spouses and Catholics. I have dated Catholics and wonder why they call themselves Catholic?!?! It frustrates me especially when they are from here. It's like why can't they admit they don't believe in the 7 out of 7. Or think that since they carry the title Catholic that everything is ok. Anyway, enough of my hogwash.
You sound like a mature girl who has found your Faith in God and what surprises me the most, you weren't raised Catholic but knew that Christ is our Savior
Anyway, just have to top everyone's numbers here for large families. Ten brothers, seven sisters, 37 nieces and nephews, lost count on grand nieces and nephews, and 6 or so angels in heaven:)
Keeping track of 3+ conversations in one room is challenging but part of the joy and fun!
But the loneliest spot is the 'head-of-family' chair just waiting for a good man to fill.
