Is it possible for the birth control pill to change how a woman feels about the guy she's with?

I swear this happened to me. I was seeing a girl for over three and a half years and lived with her for over three years. Shortly after she started taking the birth control pill just three months before she left me she changed so much. She stopped working out, stopped eating healthy, lost all interest in sex and before I inow it she lost all interest in me. I read reviews on her pill and a lot of women had bad experiences with it. One even said she felt separated from her boyfriend. I'm just interested to hear everyone's take on this. Something seemed really off to me.
