Suck it up you two - it is now time to be happy for Sarah and Patrick and baby Avery. You can deal with your issues later.
Personally, I think Bailey is carrying this a little far. Yes, she was hurt and angry by Jonny not telling her about the pregnancy scare, and she let him know it. He got that he screwed up by not telling her and he tried to apologize......what more can the guy do?
But now that he illudes to the fact that he is done, she is upset. Bailey has to either forgive him and move on with him or hold the grudge and let him go. It doesnt mean she has to forget the pain - just let him know she is willing to work with him to get past it.
