*This is long, but needed*
 

Sooooo.....

I'm running here to rant/vent to y'all because I don't have anyone to comfortably rant this to right now . And I'm usually someone who keeps things to myself, so this is a better emotional outlet. 
 

So, I have someone I've been friends with since we were around 10 years old, we met in school. We've been friends ever since, our grandparents were friends, we would visit each other every now and then, and we would vent to one another. 
But me, I usually don't say much, that's just my nature and how I go about doing things. She rants, vents to me and I'm always there to listen, support, and be a friend. 
 

Years go by, we're still friends but life has changed because we're growing up now. She has a family to take care of and I have a job and other responsibilities. One of which is to spend time with my friends. I love going out with friends, eating, drinking, and just catching up and having a good time since life is getting busy for us as we grow older. 
Now, this friend started commenting every now and then that I neglect our friendship because I hang out with my other friends. 
She claims that I don't ever want to hang out with her and that I'm always "busy" for her but free for others. 
But get this, now that I work and whatever, I like to plan my days so that I'm prepared for them. 
Usually when she asks to go out it's on a day that I've already scheduled something else. And so, naturally I suggest another time. But she starts to get mad and act like I'm curving her. 
When I ask her to hang out; sometimes she's busy as well or things happen and she cancels, which I get. It's life. That never bothers me and not once have I felt like she was neglecting our friendship. 

About 2-3 weeks ago, I suggested we go out since it's been awhile, she said okey but then later on said she couldn't make it. I was understanding. 
Then , a week after, she suggested we go out and said "You better not have plans to hand out with your other friends."

I told her my siblings and I already had plans, then she left me on read. 
 

About a day ago , I asked her to go out and she said no thanks and wrote how she was mad me and that I always choose other friends over her. But she deleted the chat message before I could read it throughly and reply to it. 
 

Now, I usually don't like to say things like , "Look at all I've done for you." But in this case I feel like I should. 
I've literally been there in her toughest times. Stayed with her for hours and hours making sure she was alright. 
And the first day she directly claimed that I hadn't been a friend to her, I had just been at her house about a week before to visit her and greet her newborn baby after she'd given birth. 

So I'm thinking to myself "is being a friend to her just about going out and spending dollars? Do those moments where I visit her and check up on her not matter?"

(And we've gone out plenty of times (Her & I).

I plan my days ahead of time because life gets hectic and all, if our days and times of availability don't align, is that suddenly grounds for being accused of neglecting a friendship?

I have a few other friends whom we don't talk for weeks and we don't see each other for months, but when we talk, it's all love and comfort, and understanding. Because life gets busy and people can't be on the phone or out drinking every minute. 
 

What's telling though is when she got mad at her other friend for apparently not talking to her as soon as they left a wedding. But I asked her if she checked on the friend either she said no. I asked her if they had an issue and she said no. She was just mad that her friend (who is my friend as well.) wasn't first to text her and stuff. Likeeeee, girly, people don't have talk and hang out all the time. It doesn't mean the friendship is dead. 

huhhhh, anyways. 

So, what does this friend wants for me?

or am I in the wrong here??
