Well, of course he lies. He has affairs and lying is included.

Jumping to narcissist is a huge leap. You don't know him well and I don't think it's relevant.

I think he's a player but that doesn't mean he is an N, at all.

Sounds like it's time to move on. Spend time with friends, hobbies, etc. Counseling if you can't stop obsessing. Good luck.
