If I want a good Catholic fella, LD really is probably the only way I'm going to find one. The ones in my home country just aren't appropriate, and the membership for this site is slim.
LDR can work, if both parties are committed to it working.
We're the Catholics, remember, we're supposed to be the ones with an irrational beleif in the magical sky fairy/flying spaghetti monster. If we don't think God can close the gap and enable two people on opposites of the globe to have a solid relationship leading to marriage, then what are we even doing?
If we can beleive that little piece of bread over the altar every Mass is Jesus Christ personified, then surely we can accept LDR can work.
