From a relationship coaches perspective, there is absolutely nothing wrong with you talking to more than one person. You are not in a committed relationship. As you said, the person that you're talking to is not only seeing other people but he's lying about it. Frankly, who cares if it looks bad to him when he's seeing other people and lying to you about it?0THIS IS NOT RELEVANT ANYMORE

If you haven't agreed to be exclusive, then it's perfectly okay to see multiple people.
But that he lied about it is what makes it clear he isn't worth your time.
So like, if you choose to see multiple guys, if they ask if there are other guys, just be honest. If they don't want you to see other guys, then they have to agree not to see other women. :)1THIS IS NOT RELEVANT ANYMORE
