It's like you are asking if it is ok that you leave your wife. You even say that there is a possibility that you could figure it out, and it would be good, but that you are just tired. Well, marriage is hard work. It always will be. Especially if you are wanting improvements in your marriage, or if you are always striving for more...which most people in relationships do.
Think about this: If you leave, and find another, would you want that person to some day say, "I'm tired. It's too much work. THere are no guarantees. I want out," to you?
You say you love her. If you do, then your answer is in your words. Just love her.
