Leo female pretending to be my friend?

I've noticed that my friend whom is a leo, is not making an effort to speak to me. Its always me starting the conversation. Naturally, I'd see it as a one-sided friendship. But anytime I get deep within asking whats the deal, or problem, she insists that "i'm fine" and that there is nothing wrong with me. Then when I'd make an offer to leave the friendship for dead, she indirectly BEGS me not to go and that she doesn't want to pose anymore friends. So now ive stood silent for 6 days, and she hasn't so much has texted me. So I tried ending it again, but again, she says she still wants me as a friend..what red flag am I missing here?

Lose* not pose.

I've had trouble with this my whole life. In my experience, I am not purposely shutting anyone out, ignoring anyone, or its not that I don't like your company. I just am usually in my own little world, doing my day to day activities, sometimes I'll stop and think of a person, want to text them and forget, or text but don't keep the convo up because I'm a bad texter, No bad intentions at all! Sometimes I'm the best texter... not much relation to how much I like you it's pretty much the same for all.

People have accused me of shutting them out of my life, not caring about them. And I am SHOCKED because I never saw it that way. Little do they know I call/text almost no one lol. Few close friends here and there, my mom, I mean Cmon now. When people start to get too clingy, have too many expectations, I feel my freedom is being compromised or I'm being accused then that is when I REALLY do start to not care for that persons time/attention. So maybe give her her space. If you really like her as a friend you will be able to respect that and enjoy her when she's ready to come around. If you can't bear to do that then really end it for real this time. What's your sign?
