Confronting ex boyfriend


Hi all:

So me and my ex bf recently broke up. The reason for the break up was lack of communication and him not being truly over his ex as they broke up only a couple of months before we started dating. Most recently, after the break up, I noticed that he is more consistent with texting me back and asking how my day is, etc. This is frustrating bc these are all of the things I wanted him to do while we were together, so now I feel that he is just playing with my heart. Therefore, my question is, should I confront him and ask why he is more consistent now? Or should I just not say anything? We agreed to remaining friends and I still care about him... so, Idk...
