No. Marrying someone right after the divorce is never a good idea, especially if you didn’t hook up with the person until you were getting divorced in the first place.
Even if you are left financially secure, a divorce is still an emotionally trying event. Jen strikes me as a fairly put-together woman, but she would be less than human if she were thinking rationally about men and relationships this soon after her cheating husband dumped her to be with the ho-bag mother of his daughter which was conceived behind Jen’s back.
If I were Jen’s invisible guardian angel, I’d will myself to stop watching her undress and take showers long enough to tell her to give it at least a year, preferably two, and that if Vince really loved her, he’d understand and wait. Then when she asked who the hell I was, I’d tell her that I was just a voice inside her head, and the best way to banish me would be to pleasure herself for the next few hours while moaning Linty, Linty using the handy-dandy little device in the top dresser drawer which she didn’t even remember buying.
