Was my ex baiting me or being passive aggressive when he texted me this?

Me and my ex boyfriend were together for 2 years and we broke up 1 month ago. I was in no contact for 30 days and he texted me for the first time and said, "I wish I never F'd up, i hope your happy and blessed now". I replied back "ok..." i wish i never responded though. That really was not much of an apology. That message made me upset.
