<human>: My girlfriend and I broke up two weeks ago and made a pledge that we wouldn't contact each other for two months so that we could try to get over each other. We initially tried hanging out as friends, but that failed (we wound up hooking up), hence the pledge.

It was a mutual break up for logistical reasons and one we knew was coming from the get go, so it wasn't a surprise to either of us, and it was mutual. In an attempt to move on I drunkenly made out with a girl who is, unbeknownst to me at the time of the make-out, a co-worker of my ex. I feel pretty shitty about it as I'm sure she'll hear about it through the grapevine at work.

While working today, I got a text from my ex asking if I needed any help on a project I'm working on this weekend. I have a feeling she heard about what happened with the other girl and is freaking out a little bit and looked for an innocuous reason to contact me. I feel like it would be a real dick move to just ignore her text entirely, and the thing is that I do want to see her, but I know it's a bad idea. How should I respond?

Can you provide a brief overview of the text?
<bot>: Made out with my ex's coworker, got an innocuous text from my ex and I'm unsure how to respond.
