I was in a long distance relationship for 4 years. (TN/MD) I just moved my girl here and we survived it.
Was it hard. Absolutely. Very. But can it work? It really depends on a few things.
How long have the two been in a relationship?
If are just getting together a few months before then no. It wont work. The two havent been through enough to have the mutual respect for each other and the time put in to know how to be with just one person. If its been years, then yes, because at that point you are already talking serious relationship territory.
How long of a distance?
If its only a few hours it can work easily, even for new relationships, because either one can go to the other one at any time.
And sometimes the distance works for the better. If its longer than a few hours away then it is harder because you have to plan visits. That also involves not
going to see her/him when she is on her cycle. There is nothing worse than going to see your girl after a few months and her being on her period, then having to wait another few months til the next time to smash. Tha'll make you want to cheat right there if you are not a strong person.
Finances:
If you are broke LDRs DO NOT WORK. You gotta have cash for trips, things to do when you get there, rentals car if necessary, hotel if necessary, emergency cash etc.
One thing neither party is going to tolerate is not seeing each other on account of being broke.
Are they the one:
Cause if they arent at least the prototype then it wont work. It will be too easy to look at the next thing. And not just for you but for her too.
Its gotta be a situation where neither of you are looking for anything because you already have what you want. If not someone WILL cheat.
Im sure there are other thing but those are a few I can think of from surviving my 4 year LDR.
