A really strange thing happened to me. 

It started after corona hit, so no girls for me the last months. After one of my best friends told me about his ex and how he fucked her and plated her, this made me somehow nostalgic for the big actions so I said fuck it I'll text one of my ex gfs. (The girl I texted, we were in a one year relationship, I actually liked her, she was fun to be around, the "I love you" - "no, I love you more" bs, took her virginity, the first girl I said "I love you", so she's pretty important to me. One year ago we broke up, typical break up, out of the blue, "we need a break" and all the shit. I moved on and that's that.)

So two months ago I texted her, and she totally rejects me, she said basically "don't text me again" then blocked me. End of story.

Two months later (yesterday) she unlocks me and starts telling me she wants to talk about our relationship and why we broke up, and shit like that. Told her to say what she has to say and she proceeds telling me, out of the fucking blue, that the sex was bad, just like that, "the sex wasn't ok", and how the sex is so important in a relationship and if it's bad the relationship is doomed. 

What the fuck? Why? I don't understand what's the meaning of this, it's even too retarded to be real. Why would you say that a year after we broke up? It's reasonable to say it after we break up, I get it, but not a year after.

I said "ok" then she said how relieved she feels for telling me that, or something like that, "bullshit bullshit", "don't block me". Told her "god forbid", she didn't answered after.

Is that something girls do often? She wants to have sex with me but doesn't know how to ask? It's the first time something like that happened to me and it's really bugging me. The meaning of this is beyond my understanding capabilities.
