Dear Prudence,
I’ve been with a wonderful woman for three years. We got engaged, she got pregnant, and we were planning a happy future together. But then many things happened in quick succession and now I’m left feeling adrift: Her father died from cancer, then she got into a car accident and had a miscarriage. The happy, bubbly person I fell in love with turned into an angry, bitter woman who lashes out at everyone and picks fights at the smallest provocation. I try my best to support her, but I’m feeling burned out and taken for granted. I understand she’s hurt and grieving, but I feel that it isn’t an excuse to scream and yell at someone just for breathing. I’m considering breaking off the engagement, but at the same time we’ve been together for three years, and up until recently, we were happy together. The other issue is that we moved in together shortly before our engagement, and we had just renewed our lease for another year. But every day I spend with her is crushing me, to the point where I dread coming home. Is it abandoning her if I break up with her?
