Did he really pocket dial me?

I recently got back in contact with an ex whom I did't speak to for a year. Long story short, I texted him to say happy birthday and then we started chatting a little (just in a friendly manner). A few days later, I got a missed call from him at 9:17pm. Two minutes later (9:19pm) he replied the previous messages that I sent at 9:09pm without mentioning anything about the call. I was reluctant to call him back since I found it very strange that he would call. So I texted him back the next day and asked if he called. I was quite disappointed because he told me it was just a pocket call. Wasn't it a bit too coincidental that he pocket called me right after I texted him and he also texted me two minutes later?

Some background info... We stopped seeing each other last year because of some misunderstanding. When I tried to apologize, he ignored me, and when he tried to reconcile, I ignored him back. I know this was really childish... At the beginning of the year, I called him a few times because I wanted to apologize but he never returned my calls. That's why I stopped contacting him completely.

Guys and girls, please share your opinions with me. Thank you! :D
