I remained with my girl after a long distance relationship
That's great. I never did a long distance one. But my brother did, and it was about 400 miles.
I feel his pain, it sucks at times.  It makes you cherish the moments you do have together though!
She was a keeper though, I'm sure it was worth it for him.
I hope it ends up the same way for me also, all the best to your brother!
