She wants us back together but doesnt want to talk to me now?

Long story short, I'm 24 and my ex is 18 almost 19.

We broke up a month ago cause she realized she still has feelings for her ex.

We'v been talking on and off for the month.

Last night I asked her "do you know why talking to me stress you out?"

She said:

"No I dont know. Now I have to block you. You dont know how to stay away do you? Talking to you gives me anxiety"

I replied saying that I didnt know talking to me made her feel that way & gave her anxiety and that I geniuely didnt have a clue.

She replied saying "Omg, this is why I dont need this. iHonestly I cant talk to you right now. I'm just so lost right now."

I didn't reply. What she said & how she said it honestly kinda hurt.

She said she wants us to get back together and she wants to get over her ex but its been really hard for her to do so. Keep in mind her ex was phyiscally & mentally abusive & shes already admitted that she knows hes horrible and that Im the perfect ideal guy for her but she doesnt want to date me again while she still has feelings for her ex.

Should I just move on for good & not say anything to her again unless she reaches out to me?
