Another thing is that she began to spend disproportionately large amounts of time with him, going as far as pushing away her friends and me. Likewise she’s been “babying” him a lot as well as excusing him of everything bad he did and fiercely defending him against any criticism. It seems she sees him as some sort of “victim” who needs to be saved.

All of it is very unlike the healthy yet deep relationship we two had where our friends were never neglected and we always exchanged fair criticism.
