Recently started a job where l was interviewed with a man for the same position. He seemed really enthusiastic about me afterwards and we chatted all weekend. We both got the job.

Everyone at work thinks we're a couple and he does flirt with me, sometimes explicitly.

Tonight he said he got out of a very long relationship a few months ago and won't be in a new relationship for 'a very, very long time.'

Obviously l don't want to split, especially on a coworker though he's complained that l give a lot of 'fine' and 'ok' answers now outside of work rather than being chatty. 

We sit together at work though should be in a new office by Monday so l'll sit far apart. I'll stop spending lunches with him and avoid instant messaging. 

Any ideas?
