Was my guy friend trying to tell me that he liked me in a subtle way?

Was my guy friend trying to tell me that he liked me in a subtle way? Because I was talking to my sister and she says that the way I described it, she thinks that my guy friend, Colin likes me. I hang out with the group of like seven people. My crush, Andrew is in this group. it’s kind of embarrassing, but I went after Andrew one day and asked him straight up if he liked me. Because some of our friends were telling me that he said that. Turns out, Andrew had a girlfriend. I went back to my group and I told them what happened. Andrew had had a girlfriend and how surprised I was by that. Because she never came up. So my friend, Colin, said “yeah he does have a girlfriend”. He was saying this matter-of-factly, but looking down. Later that day, Andrew wasn’t with us, but Colin kept trying to talk to me the entire night. I was quiet because I was more embarrassed that what happened. He kept asking me questions about myself and cracking little jokes at me. So I’m wondering, when Colin verified that Andrew had a girlfriend, was that Collins way of telling me that Andrew is no longer available but he is?
