-Suprisingly little baggage.
-Simple name(i.e, Bob Spoon, Jack Johnson).
-You found him wandering the streets with a bandage on his head.
-Honestly perplexed about the origin of his tattoo.
-Doesn't think he's ever loved like this before.
Should you break up with him?
Are you kidding? He's a clean slate. You can dress him how you like, you choose all the movies, and he has no annoying friends or family. Jackpot! The only downsides are :(1) he could regain his memory, and with it, some control of the relationship; and (2) his family and/or friends may find and relcaim him. But they might not recognize him with the makeover you gave him. Keep him while you can.
