Hi there,
I have been in a long distance relationship for almost 2-years, and I have a close friend who has been in a long distance relationship for 5 years (also across the world from each other).
Do not be scared, if it is truly meant to be then distance will not be a problem. I am not saying you won’t struggle, because you will. But it is only truly meant to be if you are able to face hardships together and make it past them.
If it doesn’t work out, then he was not the one and you can move on towards finding the right one.
Do not be afraid, as no matter what happens, things will work out for the better.
As for advice, if you truly love and believe in him, trust him. And try not to let your insecurities get in the way of the relationship.
Best of luck,
Lotus
