Well, better find out the truth late than never. If he didn't appreciate the relationship, then you're better off without him. Now that you've learned from this experience, you will find a better person. Although, I think he'll try to reach you again, but then it's up to you to either live this experience once more or find a better man instead.

Don't let this relationship affect you negatively, don't over think it. Do your best and focus on finding a new job, because you'll need to be patient about that.
