Becoming friends first strengthens a relationship. Your reasons for wanting Jodi and Bette are great....but the relationship will not last.
No, I don't think either relationship would last. However, at this time in her life I think that Jodi is better for Bette than Tina is. In the last season we have seen Bette challenged. She has had to face-up to some of her flaws and become more responsible around other people. She was with Tina for years and that never happened.
