Pot odds say call...I fold it

Folds to SB who pushes

I know I'm getting the odds to call but if I call and lose (which I most likely will with a piece of crap hand like 5J), I 'm left w/ a stack of ~1000...which means my FE will be gone. However, if I fold, I still have a stack of ~1600...good FE for when I push.

Go with pot odds and call or preserve FE for when I'm the one pushing? What's the correct move?
