<human>: So, I'm an engineer for a big company. I work with a team of other engineers to build complex systems. Recently, we hired a few new people, including a new Linux guy. I'll call him Tim. 

Tim and I get along great. He's a cubicle neighbor and we chat and text occasionally. He's building a new computer which is rockin', so he will send me progress pics and that sort of thing. Genuinely, these are awesome and I like our friendship. 

Tim is married. I just came out of a relationship with a cheating dick, and on one of my really weak days I spilled the beans to my team. It was a total failure. I just couldn't handle it, and everything was going wrong, my 7 year relationship was over... yaddi yaddi yada. So anyway, Tim was there, and my colleagues were all really supportive and we had a great night working until midnight listening to 80s rock. (And we fixed the system... yay!)

Anyway, ever since that day, Tim has been really open with me. He talks about his wife very negatively. He talks about his regrets on marrying her and how awful she is. Now, I know better than to believe what he's saying completely. There are 2 sides to every story and I don't know hers. But he goes out of his way to describe this awful woman in the worst ways. He brought up that they have a dead bedroom and that it kills him inside. And I really feel bad for him. 

So.. the problem. I worry, a lot, that he is trying to start some emotional affair with me. I don't want to put his wife through what I recently went through, and I won't do that. But as a friend he's a great guy and I don't want to make it awkward with him, even though he's making it awkward for me. 

How do I get him to back off without losing him as a friend? I've thought about dating other people and stuff to sort of make me seem unavailable but I'm really not ready for that yet anyway. Any ideas? Thanks in advance :)

Can you provide a brief overview of the text?
<bot>: Coworker may be trying to get emotional. I'd like to keep him as a friend while not going over any boundaries. What do?
