Point?

He told me today that he is involved in a relationship with her. I had asked if there was something he wanted to tell me about her, seeing as he's been living with her as "roommates" for six months now. I complimented his honesty and told him that he is worthy of love and that his choices are reprehensible. I told him that it's wrong, he's still married to me, it's adultery and infidelity. I told him that there is a standard and that people sometimes make wrong choices, but can still choose to make the right ones. I told him that it's painful for me to see them dishonoring our marriage this way. I told him our marriage is worth saving. I told him that if he wanted to move on, he could have at least waited one year and honored our marriage.
I feel like I am floating. I feel very ungrounded. Shocked. I can't remember when I felt like this before, if I ever have. Things feel very surreal, like they aren't actually happening to me.
Mostly I worry for my kids. I feel guilty. I know I am not guilty. I am not responsible for this situation. I worry if they will be ok. How is this going to affect them?
I am committed to the marriage. I told my older daughter that just because her dad is sharing his bed with another woman doesn't make it ok, and I promised her that as long as I was married to her father I would not be sharing my bed with another man. I told her it's wrong and that sometimes people make wrong choices. She looked kind of surprised when I promised her that, like her little mind was processing this new information. It felt good to be able to show her the right path and show her the right standard.
I had the same temptation he did. In the beginning of the YOW I also felt myself beginning to fall for this other guy, I put a stop to our friendship, no matter how innocent it was. I dragged myself firmly but surely onto the path I knew was the right one. And it was not easy, it was painful and challenging to pull myself away from the "falling in love" feelings I was beginning to experience, and instead to remain thoughtful about my interactions with this other guy and consciously create spiritual bonds of friendship (which is the Guidance in these cases).
I can't say the same for my husband. I pleaded with him not to move in with a single-mother when he moved out from our home. What did he think was going to happen? He told me that he never intended for this to happen... this statement just makes me mad. It's careless and thoughtless. But how can I be mad at him for being stupid? Perhaps that is his station. It seems that he is just foolish, lacking in good judgement. Of course, he is choosing the be foolish, that is another matter altogether.
It seems that I'm growing in accepting him for where he is at, and at the same time growing in loving him regardless.
He is a loving and giving father to our two girls. He has poor judgement and poor boundaries - but hopefully the girls won't suffer due to it. Hopefully God will protect them and when they grow up they will have better discernment than their father.
It's so sad. How did the noble personages in our Baha'i history continue when faced with these onslaughts of difficulty and hideousness of human nature?
When you read the Fire Tablet or the Tablet of Ahmad and you think if the immensity of Tests which they speak of, and then you think, but this is the Revelation for the next 1000 years. Things aren't going to get better! We will still be praying to God for assistance, as the "people are wandering in the paths of delusion, bereft of discernment to see God with their own eyes or hear His melody with their own ears" and the robe of sanctity will still be sullied by the people of deceit. I am asking myself, "what's the point"? Why bother?
