(best) friends

So 6 months ago or something my (then) best friend and I had a fight and haven't talked since. A few days ago she texted me to apologize and told me some stuff that happened in her life recently, as well as why she acted the way she did back then.

She was in a really toxic and kinda abusive relationship at the time and he didn't like me so he gaslit her into thinking I'm a bad friend and stuff.

I forgive her and honestly just wish she would've told me earlier about her situation so maybe I could've been there better..

Now we text almost everyday, but she only ever talks about herself and doesn't try to initiate a meet up or anything, hasn't really asked about what has happenend in my life and only talks about all her other friends while I can just sit here and listen to her living her best life while I was completely alone since we fell out.

I didn't have any friends of my own and she knows it. She knows I've been sitting in my room, no friends to talk to or to just spend time with.

Anyway, fast forward to now. She keeps talking about her ex boyfriend and about things she could do with me together to "get back at him". The only times she even mentions us doing something together are for lans she made to piss him off. Posting stories together, me texting him, things like that.

I feel like the only reason she wants to be friends with me is him not liking me. She can use me to get under his skin. I have been trying to meet up with her or even at least call but everytime I bring that up she suddenly is the busiest person to exist and then I hear all the things she did with other friends. She has the time to call her other friends everday and talk to them for hours but not even 10 minutes for me. 

I wish I could tell her how I feel, but our dynamic is still delicate, I feel like I have to walk on eggshells around her. I fear that if I do something "wrong" she will drop me again, but on the other hand I know that's not what friendships should feel like..
