Hello, I am Rafael. Thanks for asking your question - I'm here to support you. (Information posted here is not private or confidential but public).
I am very sorry to know about this overwhelmingly sad and frustrating situation you are facing.
Whenever two adults get together in a committed relationship, both must have the same rights and responsibilities. it needs to be mutual, from honesty, and respect to openness and accountability, otherwise one would end using, abusing or neglecting the other. You have been together for a long period of time, and bought a house 13 years ago, and have been married for the past year, what shows you both chose to take better care of your relationship and set each other as a number one priority in your lives.
When he decided to gave his house to his daughter without telling you about it, he did not respect a basic boundary and agreement you have as spouses, he was not being truly and totally honest with you, and that's w why you have felt this betrayed, since your agreement and expectations was to be real, honest and sincere with each other, unless you happened to have an agreement that you would not have any role to play around specific areas in each others' lives, like what you were going to do with your houses, property , etc.
His reaction, being anxious and avoidant shows he was very well aware he was not doing something right when hiding this from you. Then when he tells you that he does not see anything wrong with it, he chooses not to take responsibility for his own actions and choices, and that's very serious, since without taking your feelings, needs, expectations and your agreement into account, there is no way you could continue to build a healthy and fulfilling marriage together, no matter how hard you try, since it is always about how well both of you support, respect and love each other as a team, without one sabotaging the other or the relationship.
Does it make sense?
