From what I gather you are not into the first guy he is just there. The second guy you are infatuated with, which is why you choose to ignore the fact that he is a liar. Normally, you would realize that would be a detriment to any type of relationship you developed with him - casual or serious.
I believe aside from all of this you do not know the definition of love and should not be pursuing relationships or anything until you do. Wait a few years for maturity to kick in.
