Young and confused (long story)

I am 15 (almost 16 but I’m still young💀) I have a guy friend (we will call him jay) and I’ve been friends with him for about 4 years now. In 7th grade I liked him a lot but he didn’t like me. (I was not cute at all in 7th💀) he’s a grade older then me and so when I was in 8th grade he was in high school so we kinda stopped talking but when we talked we had very deep conversations and so when I started high school I was so stressed because I MOVED STATES! And I also was having a Qunice at the time and it was in my home state (the one I moved out of.) and I only had my bestfriend and jay (the one taking a picture and the guy in the pic) they were the only ones that were really there for me when I moved. (had more friends but they were the real ones) jay was my partner for my Qunice and later that night we hit it off and we really liked each other ,but I didn’t know what to do because I was talking to a guy that I met where I moved and I felt bad because I felt like I played jay. Now it’s the summer and i stopped talking to that guy and I randomly started thinking about him like it was so bad I started having dreams about him and I told my best friend because she staying with me for the summer and she said maybe we are met to be (“soul mates”) but I don’t know I’m young and I haven’t really explored yet because I’m still doing school and I’ve never thought of a “soul mate” I believe but I just feel to young for a soul mate. I talked to Him and told him I’ve been thinking about him and he said he’s been thinking about me too and since that we’ve been texting everyday. He’ll always be there for me no matter what and I know if I need him then he’ll even get a plane ticket just for me but I don’t want to just think he’s gonna be my “soulmate” because I’m young but he’s met my whole family and everyone loves him and he’s even sat down and had a full conversation with my grandpa!! And it’s crazy because my grandpa likes him and my grandpa is my everything! I’m just so confused and idk what to think ,I’m seeing him in July and I’m excited but I don’t want to confuse myself😣 what should I do?!
