Hahahaha... Neo's got your number, Hex.
Anyway, this gal is playing you. Both of you. In fact, you & Cain could be opposite sides of the same gal.
Listen to your gut, you know the deal. Have fun w/her, but don't get too invested b/c its not going anywhere longterm. Your mom knows and so do we. Mommy-radar is never wrong.
And for god's sake, make sure you wear a condom b/c I'm sure this gal has been (or still is) double-dipped.
Tho, if you think you might be ready for a serious relationship, why not dump this gal & find a nice girl who will respect you?
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
