A respectful, caring and loving partner TALKS to their significant other about problems. Not take it upon themselves to do something like that.

My fiance is terrified of snakes. He lives with 9 of them. He does that because he loves me and respects what I love. we do have some other arrangements that make the situation good for both of us.

If i were him, i would be having a serious conversation with her about their future plans. Its one thing for her to not feel comfortable with an animal she gave him permission to get. Its another thing entirely to disrespect him so much by doing what she did.
