Mine got more emotionally abusive with time but it was a more clandestine abuse, not outright put downs or anything - something more sinister and elusive. But then my whole relationship was a lie in order to get me to support her, pay for everything and be a slave.
Now that I am out of it, mine uses our child to abuse me, my mother, sister and family in general. She was on cocaine, but when she stopped that, started on the booze more and now concentrates her time on demonising me, making it very difficult for me and my family to get access to the child, etc.
She started out charming and sounding sincere, but once the hooks were in, it all changed, and then of course, lies upon lies, denial, destablising behaviour. etc to keep me consistently off balance and questioning my own sanity.
Your relationship sounds like a more blatant form of abuse to me. As they say, this sort of thing only gets worse with time.
