She is absolutely well rid! If I were Louise I'd be getting my best girls together, spending the next few years having great fun holidays, drinking cocktails on the beach having a laugh at Jamie dealing with sleepless nights, dirty nappies and toddler tantrums. Also being a step dad to someone else's kids (four of them!) whilst trying to keep his own kids in the right place emotionally, considering they are now a "blended family" despite hardly knowing each other. Regardless of whether this relationship stands the test of time or not, Jamie is tied to this woman and her kids for the rest of his life. Louise might not see it right now, she will definitely be very hurt by this, but in the long run, I think she will be better off.
