Search Results: signs he is interested signals

I asked this a month ago:
In a camp, I met a guy who's my senior who took part in the planning of the camp (Let's just call this guy 'A'). His friends started shipping me and 'A' during the camp. 'A' is, to some extent, a friend. If I had a question, I would be fine with approaching him for help. It's easy for me to communicate with him. But everytime his friends are around, they tease him and me and he starts to laugh and smile. I joined a dance group for a competition, representing my specialized school against others (SoE vs FMS, both schools from the same polytechnic). He came to support, but I'm not sure if he came to support me, or to just cheer on our school (SoE). Thing is, very few people get to come along to support. (only 3-4 people from our course) He also starts conversations randomly before suddenly pretending I don't exist and playing with his friends. For example, earlier today, he wished me luck as I'm emceeing for an event later with one of his classmates. Last of all, my friend who claims to be very good at analyzing body language, says that everytime 'A' sees me, he tenses up; which apparently is a sign that he likes me? I don't know how to read all of this, and I'm afraid of overthinking and then reading into something that doesn't exist.

A month later and I can safely say that I am friends with this guy. There's stuff I've shared with him that I don't share to most. Occasionally we meet on the way to school as we take the shuttle bus from the same interchange. A few days ago, we met in the shuttle bus and when he saw me, he had this really cute shy smile and then sat next to me. We were talking all the way to school even though he planned to sleep on the way to school. We don't talk a lot on text, even when I try to put effort into keeping the conversation going. This makes me a bit confused: if I was his crush, wouldn't he try to talk to me even on text? We both have a lot of common interests.

One of my male friends said I'm sending the guy I'm interested in "friend signals" so I need to start showing interest. I didn't think I am, but thinking about it I know I am. I don't text him often anymore (because he's started initiating things), I say I don't like anyone (mainly because I don't really want to put myself up for rejection), and I don't compliment him as much. The thing is, a month ago my crush said he didn't like anyone, but that things change and he thought I was cute. He's never had a girlfriend before, so I imagine he's shy with his feelings. Should I start showing interest again and see if things change or is a month a good enough sign that things aren't changing?
Weve talked for a month, most of our conversations are done by him and he's a pretty busy person so we don't really talk a lot but when do we have conversations, usually they're at least an hour long.
