Waw, she is in love, need advice/support

[Bear007]

Thanks for the support and advises and kind words.

I have to say that this thing 'I don't see you as a person in my life anymore', like she is living with me like a roommate caused pain, it hurts to see that person you once knew changed so drastically.

Had telephone talk with mother in law about something unrelated and then topic of my wife (her daughter) came, obviously my wife announced something because there was concern and she supported me - she said stay calm and don't let her ruin marriage.
She also said to think of the child, and that she will try to talk to my wife.

I responded that it is not wise to talk to my wife, that she is unreasonable right now, and that I am doing my best to save marriage. I don't know if her support is genuine?
