High school sweet heart

Hey guys so this is my first time posting something but I had question to y’all ladies out there that have married there high school sweetheart. Let’s say your in a relationship and it’s your senior year and your boyfriend already graduated but hasn’t started college yet. What do you think I should do if I want to stay with him. I’ve known him over 10 years and we started liking each other 4 years ago. I just need some helpful positive advice. Thankyou 💕
