I'm a backup.

[Rhys2001]

I am incredibly close friends with a girl, I've known her for the best part of 10 years and we love each other a lot. There has always been this one string to our relationship however, she is a year older than me so she's in the year above... can you see where I'm going with this... basically, she is very close friends with a few other people in that year group (obviously), sometimes I feel like she's almost ashamed to be my friend; she didn't invite me to hang around with her other friends (some of which I know very well) on New Years eve, so I was left to look at snapchat posts of them, great fun... and that's just one example. I just feel like I am her backup option for when nobody else is around... As much as I hate to say it, sometimes I think it would be better off if I weren't as close to her, this isn't to say our relationship always like this but it's enough to make me ask for help. What can I do?

You could talk to her about it. It's quite possible that she doesn't want to invite you around her older friends and if she admits that... The best thing you could do would probably be to try and not feel so close to her, which may sound hard and stupid, but this way you could just see her as a friend who you can hang out with, but wouldn't get jealous when she didn't invite you somewhere etc. It's most probably easier said than done, but you can't control/change her, you can only try and change yourself.

You should keep her as a friend, for that long of a friendship she cares about you, but do you have other friends too? Hang out with them more, or if you don't you should make some.
Me and my brother have a really good friend who is 3 years older, he does things with us and takes us places, but he does have friends his age too, we don't expect him to include us all the time.

[Microcosm]

Yeah, I agree with Keegan. Definitely value her friendship. I'm sure she values yours.

Try not to get too attached to her either. Whenever she needs you, try to be there for her. If you need her, she should be there for you too.

Echo to what the two above me said. She obviously values you as a friend and as a person seeing as you all are still that close after 10 years. But I don't think it's too unrealistic to think that she has her own aged friends as well. That's just the way school works - sure, I'm friends with people in the grade below me and it's not that I'm afraid to let my same-aged friends see that; but if there's a party of all kids from my class, I'm not going to be the one who invites the younger ones.
I just think you're trying to attach yourself to her a bit too much, like you expect to be invited to all of her parties because you all are close. That's realistic when you're dating or whatever, but clearly not appropriate in this setting. Let her have her space, and enjoy what time you do have together.

I have the same issue as you with my attachment. I get attached so much to an individual that it becomes overbearing. You have to learn that people need to speak to other people. I'm saying that, passing on the advice from me to you after my closest friend told me that. We don't talk anymore because I was too clingy... Which is weird for me to say because I hate clinginess. Just accept that you're not always going to be top priority but always value her as a friend. I'm sure she does love you just the same, she just needs to spend time with others too. Please, don't get down about it. I know how bad it sucks feeling second best.

It may be she doesn't realize that you are friends with her group of older friends. My sister didn't use to include me because she thought I felt uncomfortable around her friends. And honestly she may have been out doing something that she couldn't have taken you to.
She may just need time with her own friends which is okay. You too sound really close. And people that close can get burned out on each other. Maybe just hang out with you friends
There are a lot of factors. Im willing to bet she values your friendship. And I think you shouldndonas everybody was and just talk to her.
