He mentioned twice about meeting his wife and then never followed up. Do you think he is trying to tell me to back off, given he wants me to meet his wife? Or, is he trying to sway his guilt since he seems to have a thing for me. Thanks.

We haven't had an affair with each other, we work together and we've known each other for a year. He just mentioned that me & his wife would get along great & he asked me to go to lunch with them. He never followed through. Thx.
