Ex replied to my story... what to do?

Me and my ex boyfriend haven't talked for 40 days since our breakup. It was LDR (we would meet up) but we decided the long distance wasn't for us. It was a very mutual breakup but on my end I was destroyed. We were together for 8 months. At the end he said he's not sure if he wants to marry in general and unsure if he sees a future with me when I asked (but yet told me he loved me all the time). So I felt led on because he said he did, etc. (there was other things)

Anyway I posted today on my insta how I'm going to a tattoo parlor and he messaged me are you getting a tattoo? This is the first contact since the breakup... what do I do how do I reply if at all?
Also what does it mean if your ex contacts you?
