<human>: So about two months ago I started being in touch with this guy, a professor who is a bit older than I am, married/with two little children. I reached out to him out of the blue because he has written some amazing articles on a very specific academic subject (that I won't go into for privacy reasons.)

So I'm doing a big presentation/research talk on a lot of stuff he's done, and we've been getting a lot of press about it, so that's exciting!

But about three weeks ago, things have gone from a few friendly chats here and there to him gchatting me the MINUTE I sign on at 9 AM at work pretty much all day... Then if I sign back on when I get home, he will say something like "Sorry we got disconnected! I'm back!" so we can keep talking? And at first it was all academic/bouncing ideas off each other, but now it has become talking about personal issues, stuff he has gone through, problems with his family, etc. 

I wouldn't care about it so much except that he literally talks to me all day and I was just going along with it until I realized that is it normal/okay for a married man to talk to me all day long? If he has to go offline, he will continue texting me so we can continue the conversation. Nothing inappropriate has been said or happened but I'm worried that it is going in that direction. 

I should also mention that I have absolutely ZERO... not even a shred... of romantic interest in him. Just wondering if I need to start putting up some boundaries or if this is just friendly at this point.

Condense the text into a few key points
<bot>: Professor I am working with chats with me all day, sometimes 9 hours a day at a time... he is married with two little kids. Is this crossing a line or am I just making everything into something "sexual"?
