Does it show interest if a guy asks you more deep/meaningful questions?

I have a guy friend , from whom I sometimes get the impression that he likes me. We always see eachother in a group setting (we met through a mutual friend), and last time I saw him he started following up things I said with questions. One topic was about my mother, and he asked me about my relationship to her, if I wanted us to be closer etc. His questions felt pretty personal, like he was trying to get to know me on a deeper level. Would him wanting to know these things show that he’s interested in me and wants to know me better?
