I disagree again! Rick is lying to himself. The first quote is a self destructive drunken rant. The second one is followed by him saying the exact opposite. He loves bird person. He's willing to love tammy.

Even ignoring the canon of future seasons which cements this point further, it had been demonstrated that Rick believes in love, and even clearly juxtaposes himself from the other Ricks who consider their grandsons to be "just" a Morty.

Love can be an illusion of course. And it frequently is. But rick most definitely does not categorically believe all love is illusory.
