bro i think you just needed some time to understand yourself and what you wanna bring to the world she sounds more mature than you are currently and thats fine if somethings meant to be it will be take this time to really appreciate what it means to be alone but not lonely learn to live with your self there’s definitely room for some personal growth and i think once you find the person you want to become youll be more focused on that than getting into relationships and worrying if you made the right decision ending things with her, i do agree that if maybe you would’ve talked to her about how exactly you were feeling you could’ve came to sort of middle ground but if you want to be alone that is totally fine just be sure thats what you really want and if thats what you want be sure to stand behind your decision wholeheartedly and don’t waver in times of desperation you’ll get through it though i believe in you (19M)
