A long time ago I lived with my boyfriend for a few years and never met his mom, until one year she was coming from back east to visit him.

I recall telling my boyfriend how eager and excited I was to finally meet his mom.
He responds with, "Why? You'll hate my mom. Everyone does".
I told him to let me be decide that for myself, as I get along with everyone and haven't any enemies, (that I know of).

Time comes for her to arrive. We pick her up at airport. I'm riding in back seat on way home. I say to her, "I'm so happy to finally meet you". She says, "Why? You won't like me, nobody does".... Ouch!

Well, despite my efforts of trying to get along with her, make her feel welcome at our home...whatever...nothing worked.
She was a miserable woman. Angry at the world, at herself, at her son and she definitely eventually made me feel irrelevant and insignificant.
They were both right about one thing, though...I didn't like her. Although I did try.

Some people just have so much personal issues that they simply do not care to make the effort to get along with others. It's really hard to say, but I certainly would try not to allow your bf's mom make you feel as though she has a personal vendetta against you, even though I know that is a very hard thing to ignore. It's possible that she just isn't receptive of others..period.

You've received some good advice from the others.

I hope this works out for you....
