have i been making mistakes too long

[tkdmme]

so, we had dinner at my wife's brothers house last night. I have been trying not to discuss the situation we are in. however, after dinner her brother brought it up and in front of everyone including her mother he proceeded to compliment me and tell me what a great job I have been doing. He also told my wife and mother in law that I was the only one working towards healing our relationship and doing the right things and that they should stop judging me for the times that I have failed. he told them that they have no right to judge unless they were helping in fixing the situation. Her mother was offended by this and began criticizing me and told me to "grow up". At this point I lost my cool. This mother in law has been up my ass for years and I could not take her bs anymore. It probably hurt my case but I had to say what was on my mind. Although I was beyond angry I calmly asked her not to speak to me unless it was necessary. She watches the children when my wife and I are at work so there will be times that we have to communicate.
Before I left I apologized to her and my wife.
My wife's brother has been more of a father to her than a brother. Their father abandoned them when they were young. He has backed me through this whole thing and continues to encourage me and tell me not to give up.
I hope this didn't make things worse. i have asked him not to pressure her but he tells me that it is his duty to keep his sister from making a mistake that she will regret.
I haven't seen or spoke with my wife today but im sure that she will blame me for this episode as well. This soap opera continues to have more twist and turns.
