Should I add my crush's friend on Facebook?

I found my old crush on Facebook and it has been almost 2 weeks and he has not accepted. I sent a friend request and a message 5 months ago but he has not accepted. He has been online. He changed his cover photos. I found his friend who is just like a stranger on the street, but we have 4 mutual friends. I’m not sure if I should send a request to his friend and see if his friend accepts. It has been at least a week and I said to myself I would not keep friending him and deleting him when he’s online. Either I can send a friend request to his friend or I can not bother and move on? Do you think that will be bad? He still goes to college and I had to leave early, I had a huge crush on him
