It's obvious that it has been difficult for him. He looks so much more skinny and generally unhealthy, but it is his decision. I understand and accept there is nothing I can do to change anything here.
Is it, really? “Difficult” for him? I sincerely doubt it. He’s not some tragic figure torn between his “true love” and shame at abandoning his pregnant wife and toddler. He’s a selfish unfaithful idiot. If he’s looking thin and unhealthy, it’s either because OW is a terrible cook, he’s incapable of feeding himself, or I’d be just a little worried that he might be abusing drugs or alcohol. Does that seem like a possibility?
