Friend or?

Ok, so I've really liked one of my guy friends for a very long time, but am too shy to say anything or jeopardize the friendship. I think he might like me back, but I'm not sure. Ways to hint I like him? (We flirt a lot already)

Things he does

-I go to church alone, and he always sits next to me. But when my bestie came, even though he knows her, he didn't sit by us

- In mass when we join hands to sing, he always holds mine tight, and so our arms and shoulders are touching, and lingers when he lets go

- When we do signs of peace, he gives me hug, but lingers but does the pat on the back hug

- He finds any excuse to talk to me

-He mimics me. If I cross my arms he does the same. Or if we are in church and I move my legs he does too

-He watches out for me. Not sure if its as friends, but I had to usher at church and he explained everything but still whisper when to do stuff. Then when we were walking to come back, he kept checking to make sure I was next to him.

- We've gone to the drive in together. Although we aren't dating, we shared blankets, and he was obsessive with making sure I was warm enough, to the point of giving me extra blankets and offering his sweatshirt

-I went to dinner with his family, and his mom kept looking at us knowingly. When his younger sister spilt his mom's wine, it landed on me, and he got super pissed and kept checking to see if I was ok after it spilt
