Why the hell did I message my ex

[Gemini]

I did that once, and it was really just a spur of the moment curiosity. He messaged back some snarky shit about how I just couldn't seem to let him go. When I ignored the message, he messaged back again, more crap like how he could probably find a little time for me. So I messaged him and said, "Sorry, no can do. Too busy with my BF". I didn't HAVE a BF, but he didn't need to know that lol.
