Found ex on dating app?

Hey everyone.. so I broke up with my boyfriend 3 months ago on the account of emotional cheating ( he was talking to other women on apps behind my back which he justified as not cheating since there was nothing physical).
Yesterday was our final goodbye after I moved all my stuff out.. and I strictly told him that I have blocked him on all socials and his number so that he cannot contact me.

I'm so heartbroken.. and I know this is bad.. but I started using bumble to use as a distraction ( to talk to guys and have refused to meet anyone so far) .. however, today, my ex super swiped me and sent me a compliment on one of my pictures saying " cute".. I don't know what to think of this and how to react? He also sent me electricity bills which we together should pay via email..
Is this his way of trying to somehow keep his presence known? I'm confused..
