It's making it out like such a revelation wouldn't be damaging. Being a single woman and not being young is not easy. Her taking it in stride like that is unrealistic.
Ask yourself how you would feel in that situation after investing years in a relationship. Would you be that thrilled to be on the dating scene again and having to start over with someone new?
Not saying it couldn't be amicable like it has been portrayed, but this strip makes it out like there is nothing sad or difficult about the situation, only focusing on the perspective/agenda of the trans person.
