im in love I'm in love and I hate it

this blog is like my diary so don't judge me...there is guy I like (maybe love) I've known him since around the end 9th grade and I'm in 11th now and I'm going into 12th, we had a class together outside of school that my mom put me in for extra curricular stuff, it was a night school, so we had this class together we were sorta friends but once I left that class my 10th grade year I forgot about most everyone in that class, then around Christmas (about December 5th) I went to a winter ball and I went to say hi to my friend Emma, and the guy she was with at the dance was that guy I now like (I didn't recognize him then) he came up to me later during that dance and he said "hey! I think I know you from somewhere?" and I said "yeah I thought I recognized you, your face looked familiar but I'm not sure from where..." and then he mentioned that he knew me from a class I didn't know what class because he said "cc" which I went to an elementary school called cc and I didn't think he was from there, later (like a couple weeks) I saw him at my local church that I go to and he was looking at me and I saw him and he waved and I waved back then sat down, he came to talk to me after the service and I asked him about my friend that he was with, it was awkward though because he said "oh...that didn't work out" and so I talked about some other stuff and then that was also when he told me that the cc that he was talking about was the night classes that I had recently left, he came to the church a couple times after that and he has some very small talk every time. during that time I started to grow very fond of him and I wanted to see him every day, but he hasn't been to that church in 3 weeks but he usually comes every 2 weeks. I'm not sure exactly everything about him but I talked to my friend that he was with at the dance (she is my ex-friend now because she did some really bad stuff to my best friend of 14 years) but she told me that when she told him she didn't want to date he ghosted her, and the shortly after he got a girlfriend, and then she said that once they broke up he tried to talk to her again but she turned him down. (I cant ever tell when this girl is lying because she is a pick me and she chooses her lies very strategically so you wouldn't know whether she was trying to get you to dislike him by lying or not) so she was telling me all this stuff but I don't know if its true...it sort of adds up because when she said they stopped talking he posted a photo for prom with a girl but there was also another guy there, they both had there arm around her, he wasn't the one to post the photo it was the girl and he wasn't on any other place on her profile so I don't know, he still follows Emma (my ex-friend) and likes her posts and stuff. I know that he doesn't like me but I REALLY really like him, I want to figure out a way to get him to like me or at least make him interested, we are friends and my whole family LOVES him and they all want me to date him, I don't know how to do that!!!!! help please! anyone who has any similar experiences or advice please tell me!, I've tried dressing with my colors and makeup and hair that fits my face and body and colors right because I have researched my whole life since I was 10 and so I've been dressing in my best outfit and doing my best makeup with my best jewelry and poise, I act myself around him and mature , I really want him to notice that Emma isn't the only one who can treat him this way, I bet that if he gave me a chance I could treat him the same and better than she did, I just need an in! please help!!!
