line check, .25/.5 live home game

[TheChad]

Villain plays very weak tight post flop and loose/passive PF. His PF raise told me he was ahead (by more than a little).
His effective stack is $20 and I cover.

Villain (utg) raises to $2
MP calls $2
SB calls $2
I don't even have to look and I call.

I look at my cards now.

pot is $8
SB checks, hero checks, villain bets $5, 2 folds, hero raises to $18, villain calls $12 allin.

we ran the turn and river twice. thoughts on my c/r for all of it with a GSSFD?
