I think I’m the ugly friend or do I just have a bad friend?

I (22F) think I’m the ugly friend to my (22F) best friend.
My friend lost a lot of weight a couple months ago, going from a size 16 to 6/8 and has just died her hair blonde and put super long extensions in. Before this I never saw any competition between us, she is my best friend of years and wouldn’t say either of us is necessarily more unattractive than the other.

Since the weight loss and new hair colour, she is like a magnet to boys, which I don’t normally care as I’m in a healthy relationship of 5 years, however it can get a bit annoying as it’s literally everytime we go out and she always entertains it and I end up awkwardly stood on my own.
Everytime I’m with her no boy even asks for my name or number even the mates of the boy she’s talking to, I’m completely disregarded to the side by the boys and her!

When I go out with my other friends I do get asked a couple times if I’m single or whatever, but obviously not entertaining it.

My friend also likes to post the worst pictures of me, we will take loads of pictures together and she always posts the ones I say I hate or I’m not ready or just look bad in. Where as I will always post ones where we both look good.

Now writing this I’m thinking this is more about her as a friend rather than thinking I’m the ugly friend but honestly I’m just not even sure?
