The only reason Finian considers Simon a friend now is only because he's already mated to Alistair and no longer holds any jealousy over him. With a pair of jealousy-free eyes, he realized that Simon has helped Allie considerably through the years...Simon is to Allie what Jack is to Fin, besties. That being said, Hazeth is an example of "don't believe everything you hear." He's flirty, playful, and has dated in the past...but, he's not really a player as the rumors stated. Simon is a case of "what goes around comes around." As Alistair stated, for years Simon has avoided being "landed" by a needy Maiden. We also saw hints of how selfish a lover he was in his youth. If he wants Amshel (which he really, really does...Amshel is his "ideal," educated, naughty, open-minded, and beautiful), he's going to have to work for it.
