Speaking from experience, i would have to say you should wait until he breaks up with his GF before you get involved any more than already. If he felt you were really meant to be together, he would break up with his GF, wouldn’t he? He might say he doesn’t want to hurt her, but do you think she wouldn’t be hurt if she knew what you two were discussing at work?
More importantly, if you were to go further than just discussing a relationship, will you ever to be able to trust him? If he would do that to someone else he undoubtedly felt he was meant to be with, what’s to say the same can’t happen to you? It works both ways.
Save yourself a lot of grief and wait until he breaks it off with the GF. If he doesn’t, then i guss you were never meant to be afterall. If he does, i wish you the best in the future.
Was this meant to go here?
I think this is a reply to another thread. Just C&P it as a new reply to the original one: you hit the wrong button. I’ll close this one.
