I'm confused and having mixed emotions

I have been friends with one of my closets bitches in the world for 7 years now straight into college she graduated I didn't but hey that's not the case. She is my sons godmother and he loves the hell outta her with every inch in him. Recently I had my baby shower and this bitch didn't even help out nor attend. 😕 and it broke my heart I mean in half yall😩 because I also have two other besties but they haven't been There as long as she has. They know me but this girl KNOWS ME BEFORE I BECAME A WIFE A HOUSE CAT A MOMMY A SETTLED DOWN WOMAN I AM TODAY. She knew me when I was throwing that sss in a circle every weekend at the club👀 she knew me when I got drunk numerous times and slept in my car cause I couldn't find my key to get in the house🙁 she knew me when I was a total party girl and it was all fun and games. So her being apart of my life like I have with every important aspect of hers is a filing big deal. When she didn't call or come to my shower I felt uneased but it was my day so I let it slide she never apologised or shit😒 now weeks later she inbox me on Facebook saying hey girl I got your gift for Aleah and I'm off tomorrow I will swing by when I get done handling business😳 uh no bitch you won't as I replied so she didn't bother to text back she then took this to Facebook I'm not gonna be petty I will let god handle you😶 so I like the post BEING PETTY now my friends through her tell me that she said she doesn't have time for me anymore he life is much more complicated. And she doesn't understand why we are still friends when we clearly live on two different planets. Meaning I'm married with two kids now well 1 and another on the way or whatever I didn't graduate from college because I had a baby and bills gotta be paid hunni she on the other hand is not married no kids in a sorority where she travels a lot full time registered nurse and single wanting a relationship and babies. I'm fucked up about it and I wanna call her or just talk to her face to face but our mouths are soooooo outta control somebody getting a drink tossed or hair will get pulled soooo my fiancé tells me let it go it's been time and I need to appreciate the friend she was by we have outgrown one another and move on. But I don't wanna SHE KNOWS TOO MUCH ABOUT ME 😂😂😂 we gotta stay friends damn it
