You should realize that you’re one step ahead of everyone else that’s your age. You’ve had an 8 year relationship! You now understand what it’s about… whereas all other 21 year olds have no idea!
Also… YOU"RE 21! You’ve been practically married forever! Go out and actually learn what its like to be single, so later in life you don’t regret it like my brother!
He was in the same situation as you, and married his high school sweetheart. Sure, he’s married… but, whenever I mention “that time when…” he gets pissed that he never got to experience it.
In time, I promise everything will be OK with you. We’ve ALL been there… and I mean ALL. It always ends up OK, and you find someone else.
Life’s an adventure. Don’t forget your boots. There’s plenty of shit you’re gonna have to walk through along the way.
