Why did he message me?

[Samantha]

My ex and I got into this HUGE fight 2 months ago.
Where mean things were said on both sides and I thought he said he didn't want to be friends or whatever.
We didn't talk for 2 months.

I tried to talk to him a couple of times, but he never responded.
We play in the same soccer league on sundays, and 3 weeks ago, I saw him and tried talking to him but all he said was "sorry, can't talk"


I was blocked on Facebook.

Until today, when I messaged me on Facebook, saying "what did you want to talk to me about? I'm listening…." so I responded with "hi" and he goes "that's all you have to say?"
So we were kind of texting for a little bit but it's been like 2 hours since he has last responded


Why would he randomly message me??
