Is my ex just being friendly?

My ex and i work together. We broke up but we rarely talk. This week he has been talking a little more to me but not much. A few days ago we walked past each other and he said “have a great evening Miss “ and i told him to have a great evening as well.

He texted me today and said “i see you leave on lunch break you didn’t offer me any” and then texted me a few hours later and asked about my glasses


He is the one who broke it off
