Best friends?

I'm friends with this girl-named cat- and we've been friends for a few years now. But I feel like she's not much of a best friend. I mean she cares in her own way, she acts differently when shes around certain people. She talks down to me when she does something that I don't like having sex. I'm a virgin and plan to stay that way for as long as I can, she does it at least 14 times a week, that's twice a day she has sex. And it wouldn't bother me if she didn't tell me every time we talk. I know bestfriends tell each other everything. But I feel its a bit too much information, especially since after we talk I have to, "relive" myself cause I sadly imagine what she's talking about- I don't do it on purpose and I try hard not too, but I don't know I get the yearning to feel that with someone and I honestly don't want that. And then she constantly talks about her fuck buddy Matt and it drives me nuts, that's why we go a week where we don't talk cause I don't want to hear about Matt. I'm glad she gets the attention she wants but I feel like she's rubbing it in my face, which she's not. I feel like I'm being pushed away for Matt and I've already been through a 10 year friendship that ended like this. And cat was friends with the same girl as well. I don't know maybe me and her shouldn't be friends. But shes the only thing I have left that connects me to my old home town. Do you have any advice on this mess? I am definitely a basket full of messes 😂😅

okay so yesterday I had a meltdown at the stables I ride at and I felt so ashamed and embarrassed that I balled my eyes out, my instructor told me that its okay and to walk the horse around the barn to graze. Well I did that and stopped crying-thank god! And I went to check my phone after I put the horse in his stall, well long story short someone hit and run cats car so she was mad about it and so I was like, "want me to call now or later tonight?" Cause I'm usually the one that calls her when she wants to talk to me. I was hoping to call her then so that I can lock myself in the bathroom. She says no and wanted me to call her that night. Well I didn't cuz I was watching three movies with my parwnts. But I called tonight after she texted me. And it was all about how she had sex with her boyfriend while on her period and blah blah. We talked for maybe 20-30 minutes before she went inside to go to bed. I didn't get to mention what happened yesterday and I am feeling so horrible.
