<human>: My ex-girlfriend, after almost a year, texts me yesterday angry as shit over something that happened after we broke up last April . She said "You fucked me over so now I'm gonna fuck you over." She then messages my current girlfriend and tells her in short, that I am a horrible boyfriend.My girlfriend messaged me saying that she didn't care about what my ex said but that she was hurt that I had such meaningful past relationships. She said it's been consistently bothering her and that she doesn't know why. I tell her it's nothing to worry about and we discuss it a bit, but eventually we go to bed. 

Earlier today she barely wanted to talk, and we just had a brief fight where I told her that I don't want to be in a fight over something so unimportant to the both of us and our futures. Earlier I had been rushing her to just get over it, but she convinced me that she needs time so I tell her to take the time she needs to collect her feelings and move past it. She then flips on me and says that I'm rushing her too much, I'm not giving her the necessary amount of time, and that she can't handle it, so she wants a break. My heart sinks and I panic and beg her not to take a break because they rarely end up actually fixing anything. Now she's texting me that she won't take a break, but she doesn't want any intimate acts like hugging or kissing.

Is she not over reacting? She's had relationships to but not as serious as mine. This is very unlike her, and sure she can get heated sometimes, but this is a very drastic reaction. What should I do? How much space should I give her?

Give me the gist of the text in a nutshell
<bot>: Ex-girlfriend told current girlfriend I'm a bad boyfriend, current girlfriend reveals she's hurt because I had had serious past relationships, on the edge of wanting to take a break. Advice?
