What are some ways I can test to see if my guy friend has a crush on me without embarrassing the both of us?

What are some ways that I can find out if one of my guy friends has a crush on me? We are both adults but have religious restrictions and aren't really willing to put ourselves in (lusting situations) so we only hang out in group situations. I feel like he has been trying to hint to me that he wants to ask me out or that he likes me but maybe I am too blind or socially awkward tell. He is always joking with me and complimenting me 24/7 but I have never dated anyone so I think he is trying to figure out why his tactics are not working on me lol. For example he will compliment my smile and I will say the most unhinged strange thing to him instead of a simple thank you or completely ignore him and he will just stand there confused. Also my friends will intervene a lot to hold us accountable and if we are the last two or only two willing to hang out with each other they will all cancel or expect me to say now because we can not have anyone elude that we are sinning together. I know when we first became friends we used to hang out a lot alone and everyone thought that we were dating and he constantly talks about our old memories especially when guys are talking to me he will make it seem like he is my boyfriend getting close to me and bringing up stuff we used to do wanting to talk to me about it. One when it was just us he reached out for my hand I gave it to him he smiled at me and held it in his like he was going to kiss it (immediately my friend gets in between us) grabbing our hands yelling "3 musketeers" since then he gives me fist bumps. He constantly tells me how much he loves seeing me on the daily and how he would not be happy in life if he never met me. Its funny because we both are extremely socially awkward and corky so we match each others vibes so we both might be trying to communicate with each other that we like each other but we have no idea how cause we will sit there are laugh at each other with nothing even funny but it's legit or thing
