Sorry for title, I couldn't think of how else to word it...
Basically someone that is supposed to be a close friend always seems to look down on me a bit, as if I'm a bit simple, or as if I'm not as good as other people.
For example, whenever I've done something such as colour my hair, or worn something new, she'll make a big loud thing of it "wooo, look at YOU", but with a big smirk on her face as if she is thinking "oh bless her, she tries". She also makes a lot of backhanded compliments towards me and little digs, as if I'm not as pretty/good/clever as others. A group of us went out for a meal about 2 weeks ago. Friend was a bit late, and when she arrived she went on and on about what I was wearing and even tried to get me to stand up at the table in front of 4 others to 'show' her what I was wearing. She then made a couple of jokes at my expense during the evening and when I'd finished eating she kept going on and on about how I should eat more of my meal, even though it was massive and I was full! I found it embarrassing and felt very uncomfortable!
She can never ever give me a compliment or say anything nice about me at all; she will only say something if it is either a backhanded compliment or a criticism, for example pointing out that my mascara has run, or that I have lipstick on my teeth or where my hairdresser has dyed my scalp a tiny bit. She is always very gushy about others, saying how pretty/amazing/what a nice figure they have, yet can never say anything nice about or to me. She always goes on and on about others' great figures and outfits, and then always tries to get me to agree.
It is difficult as I met her through my DD, and our DDs are friends, so obviously I don't want to fall out. I dread bumping into her on the school run though as she'll either pick fault with me or be all patronising and "Oooh what get up have you got on today then?".
Any tips on dealing with her?
