I’m not sure what you want with this girl but she has a bf.
It’s usually hard to start something serious with someone who is in a relationship when you meet them. She may leave the bf and start something with you but don’t be surprised when she does the same to you.

Casual, no-strings attached fun is not the way to go with someone who is in a committed relationship. Be her friend.

No, don’t tell her. You have only been married 3 months…keep going.

That is a lot of emotional stress that you seem to have concerning your co-worker.
Where is the boss? Supervisor? Someone higher up to assist you in dealing with this?

Could be:

1) Told you what you wanted to hear-it worked and now he’s done
2) You were taking it too serious
3) He met someone else
4) You were hallucinating and all that was a trip

The good news…that’s okay. There are lots and lots of good guys in the world and most of them do that trick with their mouth where they try and talk you into bed.
