I’m so damn angry and confused help me

So for records I’m 23 he’s 19(found out from a friend) So there’s this guy that I always walk past and he keeps staring at me whenever we do. We keep making eye contact so much. At first I was like such a weirdo but then like a few months later I smiled at him idky it was unexpected and unplanned and I don’t know I kind of found him attractive and he immediately smiled back. Then didn’t see him for two months and then I saw him and I smiled and he smiled again. Then two days ago, this guy waves at me from a distance I thought it was for someone else at first but then went close and realised it was for me
So I waved and smiled and said hi and he said hi too. Then I mean I said hi twice and he didn’t say hi back he just smiled. And then yesterday this guy has a friend group right of like 18-19 year olds whatever and I smile and he just stares/ makes strong eye contact with no smile.
Is it because he’s with his friends? I was so ****ed that now I’m gonna take another route to avoid him
Does he like me by the way

It sounds like this guy is definitely interested in you, but he might be feeling a bit self-conscious or unsure about how to act around his friends. The fact that he’s been consistently making eye contact, smiling, and even waving at you shows that he’s noticed you and likely has some level of attraction.
When people are with their friends, especially at that age, they might behave differently due to peer pressure or not wanting to seem too eager in front of others. This could explain why he didn’t smile back when he was with his friends. He might have felt awkward or worried about how his friends would perceive his behavior.
It’s understandable that you feel confused or even frustrated by this mixed signal. However, if you’re still interested, it might be worth giving it another chance before deciding to avoid him altogether. Maybe try catching him alone again, where he might feel more comfortable showing his true feelings. If the interaction continues to be confusing or uncomfortable, then taking another route could be a good way to give yourself some space.
In short, it seems like he does like you, but he’s possibly a bit shy or uncertain, especially around his friends. How you want to proceed depends on your comfort level and interest in getting to know him better.

Thank you so much for replying everyone else ignoring me!! ❤️You know what I have another problem I’ll write it for you here.
So basically I have a good friend I’m not close to herwe’re just good friends. She told me that this guy inmy history class and her are boyfriend and girlfriendwhen I met her. She just told me they broke up andnow they’re back together right.This guy sits right at the back in history so I turnaround to look at the door if someone’s therebecause in our school it makes a beep sound ifsomeone is there so each time I turn he has a hugesmile on his face. Another time I walked past him andhe looked somewhere else the whole time and thenyesterday he looked somewhere else too but thistime he was trying to hide his smileI smiled to myself when I walked past him cus idk tbhand then the next day because he sits right front ofme in class and me right at the back he turns aroundand looks at me before lesson finishes. He did itagain another day as well. One day he was going onhis phone and it was only me another girl and hisfriend in that class cus all people left. I was waiting toleave at the same time as him to see if he would doanything and because I couldn’t wait that long I gotup and the minute I got up he stopped going hisphone and walked out the door.Now school ended. Lately i had a dream and he toldme that he really likes me and that his girlfriend wasjust a cover up and that he really wanted to talk to mebut didn’t because he had a girlfriend and sheannoyed him. He told me in my dream everyinteraction with her was fake and even offered towalk home with me when she was not there( in mydream). It felt so realI don’t like him but I don’t know how to react. Does helike me or something?ONE IMPORTANT THING I FORGOTis girlfriend who’s my friend told me and him to walkto class together and he I just avoided him to not leadhim on cus I like his friend yeah and then he just keptgetting shy looking at the floor whilst walking up thestairs behind me. I walked much faster and aheadand completely avoided
I’m not really friend with her anymore she’s ****ing me off anyway
