Affiliate Marketing Secrets

Not to seem full of myself, but I’m the kind of person who’s really kind and loyal and trustworthy to everyone. If a friend needed me to come pick them up somewhere at 3 in the morning, I’d more than likely be there for them.
To make a long story short, I have a group of friends who I’ve had sort of an on and off relationship since my junior year of high school. We’re sophomore in college now, but with time these issues (for me) have only gotten worse.
I stopped hanging out with them because I didn’t feel like I belonged in their “niche.” The things that made them laugh, barely made me giggle.
I guess because of this they’ve never bothered to invite me places outside of school, even up to now. Three of my good friends belong to this group, and even though I’m not close with the others, I still wanted to see them and hang out with them every once in a while.
I’d make attempts, asking what was going on and when, and they’d always say they didn’t know but that they’d let me know, come Monday to find that they’d been to the beach that weekend, or they’d been to so and so house and had a party.
When I told my friend how much it hurt that they never invited me places, she told me that it was a two way street if you want to hang out with people, and wondered why I waited for her to invite me…
…but I guess I was being silly by assuming that asking what the group is going to be doing was the reasonable thing to do if you want to hang out with someone.
She finally admitted that because we don’t hang out/talk as often, she never thinks to invite me to the places they go. And she doesn’t feel like just inviting me somewhere with them will change anything.
I pretty much ended my friendship with her and my two close others friends, because I am certain they feel the same way that she does.
Was/Is this the right thing to do? Do I need to move on and find new friends? Am I expecting too much out of people?
