love of my life?

About a year ago I met a guy on tinder. (I'm 19, he's 26) By the time I met him I felt as if every guy there not wanted to hook up and I was actually about to delete my account. Then he asked for my number (gave it to him) and then he asked to meet, which I said no to. I volunteer at a hospital and he met me at an event we had, he informed me he would be going the night before the event. After that, we started dating. (Fast forward a few weeks) I met his family and he met mine, we became official and since it was eating warmer and I would have summer break soon, we were out all the time. We had that weird feeling ppl get when they start dating. We trusted each other but we were also kinda jealous sometimes. We wouldn't say much, I mean, we talked but we had a lot of quiet moments. We were cautious of what we said and all that... it's been like 10 months now and it's crazy how much it has all changed. We are all up on each other, we rly trust each other, now we know we can say anything we want and we won't judge bc we accept each other for who and how we are and we rly just try to help one another. He's been my backbone ever since I started an EMT course (bc I also go to college) and he has helped me a lot (he did the course last semester). He finally said he loves me like a month or two ago, like really say it not just once but pretty often. I wonder if he is "the one". If I'll marry him and tell our kids how we met. I rly love him. And I hope he's the person I marry...
