No offence dude, but I think that's tripe.
It's all so relative. I've been with my lady friend almost 3 years now and we never speak everyday! Don't get me wrong, I love her too bits and am absolutely confident I'll be spending the rest of my life with her. But ENSURING you talk everyday? Nah, I couldn't live like that. A relationship should be spontaneous. I couldn't deal with a schedule like that and I know for a fact my lady friend would hate it even more!
It's cute as hell when she calls half cut, talking all sorts of nonsense in the middle of the night.
But like I said, it's all relative. That's why I think asking for specific advise is such a bad idea xD
Not sure how you think youre going to live with somebody and not speak to them everyday, especially if you start a family, good luck with that!
