He knows I like him but we're still friends. Is this a good sign?

So I have a guy that I like. I’ve tried to keep my feelings for him to myself but I guess I’m not very good at it. A bunch of us were hanging out the other day after work- we got some drinks and my best friend was driving us. There was my best friend, myself, and my crush’s brother. We were all waiting for him- my crush- to get in as well.

As we’re sitting in the van, I don’t remember who said what (I must have said something) about my crush and his brother says “Don’t worry. I know you like my brother.” To which I responded, “Please don’t tell him, please don’t say anything. I really don’t want him to find out.” And his brother responds back, “It’s fine. He already figured it out. He knows.”

Then he finally gets in the van and we take off.

So I’m curious why, if he knows I like him, why hasn’t he said anything or ended our friendship? That’s what happens every time I tell a guy I like him- I get rejected. I’m thinking that maybe he values our friendship and maybe doesn’t want to ruin it?

But my best friend and I have had many conversations about this, and she said she’s be “watching him” when we’re around each other and she says she really thinks he likes me- he follows me everywhere, he’s always coming up to me and talking to me, he faces me when talking, he looks me in the eyes, if I go out for a break he comes out with me. Even if he’s not right on my heels, I’ve gotten to a point where I can predict, if I step outside, within 2 minutes he’ll be out. He has broken down and cried in front of, he’s given me some insight into what things are like for him at home (he lives with his dad and brother) and it’s not good, he’s even open about his relationship with his ex and how she absolutely broke his heart. I also do not know how long he has known, but I did ask him the other day if he wanted to go to the movies sometime this week- maybe hang out a little before and have a drink or two- and he responded “Yeah, definitely.”

Now, all this said- I am inclined to think he likes me too- but why would he not make a move if he does like me? He knows I won’t reject him, but he hasn’t said how he feels or anything. He’s not particularly “touchy feely” with me, there’s no physical flirting, but again, my friend claims she seems him flirting all the time.

I really like his guy and want things to work between us, but I also don’t want to scare him off or potentially ruin our friendship. Maybe he’s afraid I’ll just break his heart too? Or maybe he just doesn’t feel the same way? I don’t know. I am so confused. Any help or insight would be greatly appreciated. Thanks :)
