No, it doesn't. It's SO hard for me to find a mormon boy who can handle me...who is someone I want...who is INTERESTED in me. But it's more important to me to marry someone in the temple than to find someone I can't. I mean, it is our belief that a marriage sealed in the temple lasts beyond this earthly life, so to me it'd be kind of stupid not to do that, as this life is short compared to eternity. Aside from that, I wouldn't want the issues of trying to raise my children in an LDS home and have their father be of a different religious view, regardless of whether or not he did or didn't care what religion his kids were. And some other stuff.
No, it doesn't...
It doesn't forbid that I marry outside the covenant either, but I can't marry in a mormon temple if I do, and it's very important to me that I marry in one.
I myself can't handle long-distance relationships though, 'cuz I'm clingy and stuff and I need the guy to be here for me physically. I've tried doing long-distance relationships and they mostly end up in me getting hurt.
