Guy's and friendship/relanship question. Best answer 10 points!?

So me and my crush both like eachother and are friends/crush. He asked me out a few times. But when he shakes my hand its like really firm.( My handshakes are soft/normal I might squeeze if my hand is squeezed) Almost like it hurts. I do like it but why is it soo tight? Is he tring to break my hand? And his friend gave my a really tight firm handshake (looking me in the eye) It felt uncomfortable kind of and like held my hand for a while while he talked to me. I don't like his friend for sure (in that way) and his friend doesn't like me for sure so this was a first and it was weird. Why do him and his friend squeeze my hand hard, long, and with eye contact.
