There are many others here who have walked the path you are on, but I haven't, so I will not tell you to act. What I see is that this is where the IC might be helpful for you. You have a lot to accept that is unacceptable. My fear is that you will choose to act one way, but his actions will continue to anger you, and you will explode, revealing that you have been "acting" all along. In the end, I don't honestly believe most of us can "act" anyway that is not genuine for a long time.
