Is this platonic ?

I met a new man at work around October. For a few months, we occasionally spoke, but there was a spark that hinted at something more. We have begun to hang out more and more lately. He’s very shy and has intense anxiety around women. Recently, we were at a coffee shop together, and I bent over to grab something. He got a good look at my chest accidentally since my blouse was low cut. He immediately turned away to the side and looked awkward. He did speak to me a couple of times after that, but was careful to maintain eye contact and stared intensely at my eyes. I’m not able to decide if this is just because he’s shy or it is now clear that he is not interested in a relationship? I sent him a random text yesterday and no response yet.

He sounds like he was embarrassed at seeing so much, so to speak. Perhaps he doesn’t want you to think he was ogling, hence maintaining eye contact now.

I don't think not ogling someone's tits is a marker of whether one wants a relationship or not.

I would think he didn't want you to think he was ogling you so kept his eyes firmly on yours rather than below (which I think is a good sign in terms of respect) . The unread message could simply be that he doesn't look at his phone much (I often never look at my phone during the day and leave messages for hours). I couldn't say whether he fancied you but worth developing a friendship then maybe asking him out? If you like him if course.

Exactly this. If you want to know how he feels maybe just ask. Not staring down a woman's top is the respectful thing to do, it in no way indicates if he is attracted to you or not.
