<human>: Can you summarize the given text in a few sentences?

So I decided recently to be mature put things behind me and contact my ex. We broke up in April and I decided to Facebook message him a few days ago seeing him come up as a friend suggestion. 

I didn't think much of it or he'd reply. And so I just decided to send him a friendly  message as an almost 'I'v gotten  over the break up and want to be friends'... message saying:

'hey how are you be nice to see how you're getting on?'

Anyway a few days passed and I forgot I messaged him and then boxing day early morning ... got got a reply at 2:40 am. . . Woaah! I wad beyond surprised and didn't think he'd reply knowing what he's like. Quite honestly I thought he'd forgotten  I existed...We dated for about 2 years very over the top serious... and broke up because he wouldn't emotionally commit and I had anxiety (that I'm now over almost)and i went a bit crazy gf on him as he was acting weird. 

Anyway my question is for the men and I guess girls too if you've experienced this. . . 

What does his reply mean? Is he just being friendly like I was and am I reading to much into this? 

Thanks :-) x
<bot>: ex replied to my message acting normal and kind and I don't know why...We didn't speak for almost a year and broke up badly.
