Reconnected with my ex recently and invited her over to watch anime, we makeout etc & she denies my advances to take her pants off so after the episode goes off I take her home. Today she texts me this:

Yesterday reconfirmed that I just don't wanna do it anymore. The fact that your whole mood changed when I didn't want you to take off my pants was fucked up and you're not gonna make it with any girl if you keep acting like that. Bye.

What should i reply if at all?
