Jim is actually sick in the head. And Sarah is a pathetic doormat for accepting his rubbish. He never recovered from his divorce. And much as he belittled Tanya and put her down, he clearly considers the years he was with her to be the best of his life.
And whatever he’s currently got going on just isn’t pasting muster. He’s behaving like a middle aged man reminiscing on his youth. Not a still young guy who should be in the prime of his life! Newly married, a baby, a life free from the worries and stresses of a gruelling 9-5. He’s living the life of Riley, but looks dead behind the eyes every time I see him.
That’s what he gets for rushing into such a super serious rebound relationship after Tanya. He should’ve just relaxed and been single for a while and took time to reconnect with himself and the direction he wanted to go in with life. He was so eager to stick it to Tanya by locking down and parading a model type gf, but all he’s ended up doing is cutting off his nose to spite his face.
