My ex and I broke up 2 weeks ago. Today we met up to "talk" about things and it went really well and we decided to try and work on things. After we were done talking we started to watch tv and his phone kept buzzing on the table. I looked at it and it was notifications on Bumble. He asked me if it bothers me and I said no because I didn't want to argue. Should I be concerned? I had no thoughts to move on so close after our break up. Should I say something or just leave it be?
