My crush crushed my heart. Did I misread the signals?

Anonymous
Ok, so long story short, there’s a guy at work I have a crush on, lately I feel we have connected a lot more, my closest friends who happen to work with me, are convinced he likes me back and in different occasions have pointed out this without knowing that they all have picked up in similar things.
my crush and I started texting a few weeks ago, and I felt like everything was going great, we have this playful thing were we are always playfully touching each other, punching each other’s arms, touching each other’s hands, he unexpectedly touched my face twice to show me he was cold.
I made him a birthday card and he loved it, he still has it pinned on a board in his house where his friends can see it! (If a girl gives you a bday card made by her I think is pretty obvious she likes you, would you pick up on that guys?) when I made the card he wasn’t working but when I told him and sent pics of it, he asked if he could come and pick it up from work.
anyway to me everything was going well.
last night we were at a party and our glances would keep meeting each other, we always have lots of eye contact and smiling, always, so we also danced made a few pics together.
He texted me today and we were speaking about deeper things, truly opening up (I thought it was great) and then... he told me he just met a girl (for a second I thought he would mean me) he told me he didn’t know if he liked her or not but they had spent the night together (my heart broke and just as well he told me in a text, I’ve been crying since) I feel so stupid, I really thought he liked me, did I misread the signs? Where did I go wrong? I didn’t want to show my emotions so I said to him he should spend more time with her ( tearing my poor heart)
guys help me please, did he even like me? How did I get the signals so wrong? Should I actually confess I like him?
thank you so much for reading and answering
