I don't like to bet because I don't like losing. But in this case, I would bet that while he is gone he will not say ILY if you don't say it first, and he will not mention dialogue. If you put the ball in his hands he will drop it. He has shown you that everything else in his life comes first before the marriage. While he is out of town it will be even easier to ignore his homelife. The days will go by and you will get angrier and angrier about his failing to pay any attention to you. So, I think, if you are going to become angry at his failure, you should stop this test now. He will fail. The only reason the ball is in play is because you have kept it going.
