confused

I have a crush on this guy, and I told him via text message that I liked him. He apologized and responded by saying that he had a hard time knowing when someone likes him, he told me he thought that I was great but he's not looking for a relationship. He also told me that I was braver than he was. I don't necessarily act like I'm interested in him when I'm around him, simply because I am shy. Whenever I text him he sometimes mentions or asks about another woman. I am familiar with this woman because we are kind of friends. He follows her on social media and I notice that he likes a lot of her posts. I've noticed the he rarely likes any of my posts and never likes my pictures. I got a little jealous and blocked him on social media in an effort to try and get over him. Anyway, whenever I see him he seems excited to see me, and every time he gives me a hug. one day I told him I was leaving for awhile and he gave me the biggest, tightest hug I've ever gotten. I literally felt like he was going to fracture my ribs. I have to say the hug was amazing and I loved every bit of it. the other day he saw me and just came up out of nowhere and gave me a hug. I recently texted him to see if he was interested in hanging out outside of work. He said of course but didn't take it any further than that. Im kinda confused. I desperately want to get over him because I don't really feel like he is interested but at the same time, I feel like he's sending me mixed signals. if he's truly not interested in me then why does he always watching me and gives me hugs me. I don't get it.
