is the woman like that all the time or was it out of character? They say you speak the truth when you're drunk... it would make me vey cautious. You're a mum yourself now, your partner's mum and her behaviour isn't your responsibility you have enough to deal with. Does she think that her son isn't the father? If so that isn't going to change just because she has apolgised or was she just being an idiot. She is old enough to kno better. What does your partner think?
