I suggest that you do a search on LDR's on here. There have been some recent threads that might help.
I, personally would not put the time and effort in. They don't fulfill my needs even remotely. I just end up aching, lonelier and the NRE lasts way to long.
Really it sounds like any other new relationship to me. There are kinks to work out and NRE to go through just as anyone who lived close to you. Perhaps reading on here in terms of other related topics will help.
Anyone want to be friends on Facebook?
