<human>: Can you give me a shortened version of the text?

My ex and I were in a relationship for a little under a year (10 months). We spent A LOT of time with each other. We decided ultimately that we weren't compatible as we thought.

It was a bit sad, but it was NOT messy at all. NO fighting, just words. He said that he wanted more space for himself, that he was going to focus on himself and wait a while before dating again. I felt the same, but I miss the companionship quite a bit.

5 days after we break up, my friend told me that he's back on OKCupid. How do I even react to that? 

He's pushing so hard to be friends right away, and initially I agreed, but I just want to curse him out for (what I perceive to be) lying.
<bot>: We dated a bit under a year, and under a week he's back on OkCupid. How should I react?
