We live together for around 2 years now. Usually she's ok but sometimes makes mistakes and I usually point it out, she promises that she won't do it again and then after sometime forgets all about it and repeated her mistakes. For eg, 2 weeks back we went for a drink with her friends, I was feeling sick so wanted to come home. She outright said no, so I had to come home alone. She later came back at night all drunk but next day appoligized and as Easter was coming up promised no drinking till Easters. But few days later she alone went out and returned all drunk late at night. This is just one example, things like this happens a lot! We had fights before, ending with her promising me she will not repeat it only to repeat it after a few days when I have forgotten all about it. Now I am frustrated and ignoring her altogether
