In IT, we call it 'analysis paralysis'. You can logic and talk the thing to death and never get the project either off the ground or finished once you start.
Someone (it wasn't me...) said that CM was a 'Catholic Debating Site' instead of a "Catholic Dating Site". Do we pay too much time looking for reasons why not rather than reasons why? I know, there are issues to solve (LDR, anyone?), and things like that...but, if we're here to find a companion on this journey, with God, to our salvation...then why in the h-e-double toothpicks do we place so many roadblocks in the way.
I have to state, for the record, that I'm here to interact with like folks, not looking for (and after a year from May, will be impeded from due to diaconate ordination, all things being equal) marriage, but, as one who was putatively married, went thru an annulment, and has lived as a single person since the 80s...well, I see in pastoral circumstances, and have heard, every excuse, mirrored here, as to why NOT approach the sacrament (and there are reasons why not...but they are few and far between) and trust in the Lord's goodness and guidance.
Not minimizing the possibility that there are just some things which you do have to be careful of (abusive partner, substance abuse, criminal activities, etc), which I would counsel the non-involved party to high-tail it in the other direction. But...'he doesn't like it when I _____" or "she says that she wants to do ____" is a sign of inflexibility or rigidity, not one of loving acceptance of a partner.
Donna: that 80+ year couple. They trusted and made it work. As the Lord says "Let your yes mean yes...and your no mean no". If folks are serious, you make it work. Not just for when you're slim, she looks like a model...but when the kids come and are screaming at each other in the den and you're trying to work, you're sweaty from fixing the yard...and the thin grey hair replaces the thick tresses of youth...and the face lines, and things sag and wrinkle. You make it work. Both of you.
I once started a thread about how we put our own roadblocks in the path of our own success.. I think it was the first thread I ever had to lock at 200.. I like to think that most people come here looking for a spouse.. But I also think that many sabotage themselves by not being open to what God places in front of them.. YOU may want a supermodel, but God may want the 'few extra pounds' school teacher that pops up in your matches for you.. I also think that many people have very unrealistic expectations of who they can really attract.
