Steve cheated when she was pregnant with Woody. It won’t stop, she thinks that 2 hideous tattoos and a marriage stops a man from cheating, absolutely not. If a man has no respect for his partner, which Steve publicly proves is the case, then absolutely NOTHING will stop him doing it again. He got away with it multiple times before, he’ll get away with it again because he knows she’ll never leave him. She isn’t capable of driving to the nearest town without him so there isn’t a chance in hell she’ll leave him. Hopefully Steve finds a woman capable of raising and loving children right so those 3 kids at least get a decent step-mum since their own mother has the maternal instincts of a grain of sand.
