Dating someone who is married but separated

Hi everyone,
I (34f) met a guy (36m) a few days ago. He messaged me on reddit, said wanted to get to know me after seeing some of my posts/comments around. We had a very nice chat that basically lasted for two days and he was clearly interested. I was too. I said I was looking for something serious and he agreed.

I also said I don’t have a lot of baggage relationship-wise and that I was looking for someone similar. Like I don’t have much experience either, never had a long term relationship. Didn’t have hookups and so on. He said he understood. I am kind of flexible on this but his situation seemed a bit extreme to me.

He basically told me that he’s “technically”
married. He got married two years ago. The marriage only lasted three months and he’s been “single” for almost two years now. The divorce process is apparently taking long because they couldn’t agree on things. He said it would be finalized in 2027.

I said I didn’t want to continue talking to him. Was this an overreaction? Because he was pretty great except this but even thinking about dating someone like this and waiting for the marriage to be officially over gives me a lot of anxiety.

I’m just curious I guess. What would you do?
