For sure man. You obviously care a lot about her. Either result I guarantee you'll be fine. It's a learning experience. I assume she's your first gf or first girl you've loved?
Yeah first real girlfriend, first girl I loved, first sexual partner.
Just about everyone falls super hard for their first love. Eventually they become a crutch and if the other bails you fall flat on your face. You'll end giving to world to this person. Regardless of what happens you should really start focusing on yourself and stop revolving around her world. If shit hits the fan you'll be a lot more prepared. Reconnect with friends, start doing old hobbies or find new ones. If you guys stay together she'll find it attractive by your independence and confidence. If not, you have a jump start-it'll be rough but at least you something to keep you busy, have your buds to hang out with and retain your confidence.
Guys get a bad wrap about screwing girls over, but I've heard so many stories and have had an experience where girls will line new shit up before a relationship even ends. Not making an assumptions- simply just keeping you prepared and your mind open. Bitches can be ruthless.
