Friendships Later in Life

So as I sit here writing this feeling upset and asking where things have gone wrong, I just have no answer for myself.
So ladies please tell me there still people out there who look for friends later in life and manage to find people who actually take the time for you, plan stuff with you an don't cancel.
I have always been a happy go lucky type of person who has had a great circle of people. But as time as gone on I have found people have drifted away in other circles and I've been left behind.
I am a great friend, I have so much time for my friends and would do anything for them. I love to see people succeed.
I miss not having people contact me asking me if I'm ok and how are you? I am the one to contact. I also get the we should catch up soon but these things never eventuate unless I make the contact and then usually ends with sorry can't make it today.
I'm a family person and have 2 kids and a hubby, but also love doing stuff outside of the family. I like my girly time and being around my friends. I hate gossiping and bitching and found as life goes on there is so much of it. I am an open and honest loving and caring person who has so much to offer.
I don't really know what I'm asking but guess I'm ready to give up and just crawl into a hole. I feel like noone would notice.
