Can I be honest?

OK, right now I only continue to read this manga because of Azu, because I want to see her get a happy ending.
With each new chapter I'm getting angrier and angrier and incredibly frustrated because of Junpei's behaviour. I really want to beat the life out of him! Why is he being so wishy-washy with all this situation? Going back to his wife and cut all contact with Rina was the final decision. Then why go back to help Rina out? Can he not see that he's sending her the knight-in-shining-armour-coming-to-the-rescue idea? That she's getting her hopes up with his behaviour? Maybe the author wanted to profile Junpei as a man that, even though he commited a grave mistake, is actually a nice guy, because he is concientious and guilty of the mistake he made and is trying to do everything and anything to atone for what he did and the suffer he caused. However, right now I only have one word to define Junpei - weak!
I want to see Azu thrive through all this shit and see everybody else go to hell.
Is there someone else feeling the same?
