What are the chances I (F34) am being super-ghosted or is he (M37) figuring his complex situation out?

Let me start by saying I feel like I'm way too old for this.

I (34F) am recently single and to be honest it's been a few years since I really felt a connection with someone that wasn't somewhat forced.

Through a very strange twist of events, I ended up connecting with this man (37m) in my city. We're both from the same country, he's actually a somewhat successful podcaster in his genre (history), and I dmed him when I realized we both live abroad in the same place.

To my surprise, we started chatting, which became a daily thing for a few weeks. Early on I put it out that I was down to grab a drink, and last week he said he made sure he had time off on the weekend and asked if I wanted to meet.

It was amazing you guys. We met at a bar and talked for 5 hours, we only had a few drinks but sat and talked for ages. We connected on everything, laughed so much, care about the same stuff. There was heavy eye contact, light touching, and we both lost complete track of time.

When we left, he asked me if I want to meet the next day, which I never would have suggested myself but I absolutely wanted to.

However, he's not really single. He is in a complicated, LDR with someone in a different country (not our home country) who we hadn't seen in awhile and he "doesn't know what's going on with it or if she'll come back".

Obviously bad. He made no indication of this, and from the way we talked and he asked me to a bar one-on-one, I was surprised. I mean, it wasn't explicitly a date but... Come on.

So now he's made a complete 180°, he hasn't just left me on read, he's stopped opening texts mid conversation a few days ago, which feels so much worse than being ghosted.

What are the chances he's conflicted and figuring out his situation, and what are the chances he's just washing his hands of this?

Edit: thank you all for knocking sense into me. I completely agree I wouldn't want to get involved with him further while he's still in a relationship. Following our date, I sent him a very up front text saying that I can't see this progressing now but I would love to keep getting to know him if he was available in the future, and he didn't even open it. But he's still viewing all my Instagram stories... Like a child.

I thought men would get more mature as they aged but here we are pushing 35/40 and it's the same old thing.
