Your fears of loss and concerns about losing the partnership are poisoning your LDR. You’d be OK even if you weren’t in a relationship with him at all, your mind stops poisoning the relationship, you relax, and you are finally able to just enjoy him as he is without needing him to be something when you can show your mind that.
This is actually real for just about any relationship, as they are, even if you’re not in a relationship with them at all whether you share the same bed or you live 3,000 miles apart: If you are truly compatible with someone, you’re able to love them. You merely love as they are that they exist in the world and you enjoy them.
So release – enjoy them while they’re around, but be okay aided by the proven fact that some one could show up on his end or on your own end and, in the event that relationship with this brand new person that is local to be much much better than that which you have actually in your LDR, the partnership will end.
