Help...

Okay, usually when I post in the community, no one ever responds, so I just sort of stopped posting, but I need to post this time...this boy I've liked for months, we would talk on and off as friends, and each time, my feelings would get stronger, so I decided to just stop talking to him at all just to spare the heartache that I would get because I knew he didn't like me like that, but occasionally, he would slide up on my snap stories and say things like, "you down to smash yet?" and he was always joking so I would always reply with "hmm, let me think about it.😉" joking back. Then a few days ago, he slid up on my story for a "tbh" and I put, "you're chill and fun to talk too and since you always ask, I'm down to smash" (I was joking like I always do), and he got serious about it and said, "wait really?" and he was actually serious about it, and since I already liked him alot, I told him, "I mean, yeah as long as you are." and he told me he was so I asked if he was serious about it and he said "yeah, I am. are you?" so we've been talking the past few days and like talking dirty and stuff, so I started to think that maybe he likes me now. Well, so for the last few days, with that in my mind I've been kind of happier and have had more hope than usual. And yesterday, he sent a picture with a quote on it to all of his streaks on Snapchat , which included me since we have a streak, and the quote was something about hating getting mixed signals. it kind of confused me bc since I thought he liked me, I thought it was about me and I was wondering how I was giving mixed signals. But I tried brushing it off and forgetting about it. Then, Earlier today I even thought to myself, "wow, I never actually thought that he would like me, I guess some things you wish for really do come true." and that went downhill...because a little bit ago I posted on my story a list that someone else had on their story, and the list was a bunch of things that people could pick from that they wanted from you since 2k17 was almost over. For example, some of the things on the list were to hangout, phone number, to become better friends, and just stuff like that. This boy slid up on it with 2 things he wanted, and one of the things he chose was to be "FWB" which really hurt because I thought he liked me but, clearly he doesn't like me enough...clearly, he just wants to "smash" and just be friends. I don't know if I'm overreacting, but it definitely hurt.

*UPDATE*

I didn't clarify when I first posted this and I'm sorry for that. The whole problem I'm having is, I'm almost 99.9% sure he doesn't like me like that because on the list there was also the choice to be more than friends and have a relationship and he has known that I have liked him for months, but he chose FWB over those... So, I guess my whole problem here is since I like him, do I go ahead and be FWB with him, or will that just hurt me more in the long run?
