Which boy should I choose?

I spoke to this boy on tinder about a year ago. We “talked” for a few months and just fell off. He lived three hours a away, and we talked about how when he transferred to a university in my city the next year, we would be able to see each other and finally be together. After we fell off, I met another boy of whom I have been dating for 7 months. I love him. But then the other boy came to my city, he texted me, and ever since then, he has been all I can think about. I want to be with him. I do. Love at first sight kind of thing. Turns out it happened for him on tinder a year ago, but it only happened for me when I met him in person. But I’ve been with this other guy for 7 months. I don’t know what to do. The guy I’m with now is funny, smart, the marry kind of guy. But the other guy blows him out of the water. I can’t explain it. I don’t know what to do. The other guy has given me an ultimatum... it’s me or him... My current guy is better off for me in the long run I feel like, but I want to be with the other one. I don’t know why. I’ve never felt this way about anyone before. I’m 19 years old. Who should I choose for the love of god because he’ll if I know...
