Does my co-worker has a crush on me or just friendly?

I met some really cool co-workers in another dept at the end of last year. I told them they’re like “work family” to me and I gifted them each one of them a single gift for the new year that made me thought of them with thoughtful cards I had written 🥹🫶🏻 Surprisedly, in the following week of the new year, one of my male co-workers in that department bought me a bunch of cute stuff in a gift bag for me… I was very surprised, but touched and happy. I was not expecting anything because I just wanted to give them something to feel special and recognized what they mean to me. It made me remember before he gifted me this… he was giving me overly compliments at work about my personality and he started messaging me a lot on Instagram.

However, he stopped messaging me a lot and was abit distant after the gift giving. The following week, I recall he was talking in a low volume with two of the girls co-workers about how his ex and him reconnected where she wanna get back with him while he just wanna remain friends and he has a girl crush he cares about more. He was asking them on advices. I thought to myself why didn’t he include me in the conversation and wanting to respect his space. But I also don’t think that girl crush he is talking about is me. I don't know how I feel about him with our age gap and other things. But I really like him as a person. I’m just curious as he gifted me really cute things and then became abit distant. After that weird week, he was back to normal at work. But we don’t talk as much as we used to lol. I’m also very busy at work. Tbh I don't know why he brought me those gifts since he never shared why….
