She said it's just for sex as she had been feeling really horny.
Does that work ok for you? I think if it was me with my ex any intimacy would start to make me hope it could be something more. Fine if you can separate sex from emotional attachment but could be more difficult otherwise.
I still love her and miss her but she said she move on already.
But she wants you to still have sex with her? In that case why can't she find someone else to have sex with? Fine if you're clear on it and feel you won't get hurt but it sounds a bit like there's potential to start using you. Sorry if that is blunt but it's what it feels like.
