I really get the touchy subject feelings. My life has been touched by a close one’s addiction, it wasn’t a long ago to have the effects lessen a bit, and it’s very, very difficult to forgive and let go. I think for some betrayals, when it’s a huge one, the relationship is shattered into tiny pieces and it’s not worth it to forgive, even if the other person is remorseful or addicted. For the sufferer to go onto a peaceful life, it’s better to walk away and close the door.
I could not forgive in the situations where a parent abandons a child because he/she is too young/party happy to handle child raising. This was a storyline in Younger tv show, and I did not like the mother for that abandonment act. (She did it for a different reason-because she felt she didn’t have an identity anymore as a person, just a mother to 2 young daughters and a wife-still an immensely sucky reason)
Then don't have kids then. Know yourself. Some people feel they don't like kids/want to pay more attention to their career, and so they don't have kids. Don't have a kid to set them up to suffer tremendously for your selfishness.
Regarding the 22 minute comment, yes, maybe it isn’t that they only have 22 minutes, but they executed a less developed story than they usually do when they have done better jobs of completing a story and character development in multi episodes.
