Not sure what I've done wrong.

[Confused2015xxx]

This is actually about a friendship but wasn't sure where to put it.
Anyway a girl I've been friends with for over 10 years she goes through phases of bothering with me then not giving me lickings of a dog.

She always when we are out with her friends seems to say things to me like "god your so skinny" or makes jokes about me.
Anyway last week we had a couple of things planned.
We went out on a night out and went to a concert.
Just read on Facebook she's having a girls night out next week and hasn't bothered inviting me.
It's in the town where I live and the pub is literally 3 minutes from my house.

It makes me a little sad as I don't get why.
This week she has been odd with me not really speaking and I wrote about my new job on Facebook not even a congrats,
She always makes comments to me that try and put me down.
Maybe I'm being silly but it's upset me.

I wouldn't be friends with someone like this. Ditch her.

Here's the thing I don't get. We all have different circles of friends. We sometimes want to see different people without additional people there. There's nothing wrong with that surely?

She has every right to organise a get together and not invite you IMO. It may not be about you, but about a group of people that want to get together because of them. Does that make sense?

Re the FB. you do realise that posting on FB doesn't mean everyone has seen it??

Get yourself a good circle of friends yourself and just get on with it. If she makes you feel low after you've seen her then just stop seeing her. And unfollow her on FB for the time being.

She's not your friend.

If someone keeps making personal comments about in to get a laugh in public then they are not your friend.

I would always be polite but detach from the friendship entirely and never socialise with such a cow again.

Of course there isn't but these are the same girls we go out with all the time.
If I did the same to her she would go ballistic.
I've never done anything to annoy her(I don't think) yet she can't help but make the sarcastic comments
(You buying new clothes again,your wearing too much makeup or she's a little slow and laughing.

She sounds jealous of you. For the public humiliation alone, I would ditch her. Why would you want to be friends with someone who is mean to you? Life's too short.

She needs to put you down. That's bad enough in itself but in front of others is that bit more vicious.

Could she be jealous?

Walk away. New friends time.

It's worth feeling lonely whilst you make new friends. Nothing is worth being made to look like a very who keeps going back for more mistreatment.

The strange thing is when it's just me and her we have a good time it's just when there is others around she does it.
She's actually just invited me there.
Not sure if I'm going to go as I normally end up feeling awkward

Phase her out, she's a tit, I wouldn't have friends like that.

Have you tried confronting her about her behaviour? Maybe it's a confidence thing on her part and she doesn't realise how mean she is coming across. It needs addressing though and you need to make her stop but it won't stop until you say something.

Why should you lose out on a group of friends because she's being an arse? Try getting to know some of the others better and see if you can make new life long friends. You shouldn't be feeling like you don't want to go out because of how she is treating you. Just speak to her and hopefully things will iron themselves out. Maybe it'll be the kick up the backside she needs.

she is using you to get a cheap laugh in front of others because she knows she can.

She is not your friend. She's just using you.

Sorry.
