I need to get this off my chest

Hello ladies, even though I really like this guy I’ve made the decision to love myself more instead of living in a world full of wondering, being the one who chases, and being seen as an option. I’ve decided to go full no contact, before we would basically talk every day but the last time we talked his words really hurt me and I got that feeling of being so tired that I didn’t even want to tell him anymore and I didn’t even want to argue anymore because is happened so many times before. That being said the last time we talked was last Friday. Saturday morning I woke up to “have a great day, just passing by to let you know I got amazing sleep” I read it and just left the message there with no response. Since then I have not received another text message from him but on social media he has responded to some of my instagram stories, not in sentences but just comments that could spark a conversation. Why is he doing this? The reason I don’t delete or block him off social media is because I believe if I do that I show him that it hurts so much that I can’t even see him and that’ll grow his ego even more and I want to be able to face things and overcome them without the need to block or delete. His comments don’t phase me or make me want to talk to him because I won’t cave. One day he’ll realize what I had to offer him was sincere and honest and he took me for granted. But I will not cave and talk to that man again and I’m about to be a week strong by not messaging him and not responding to anything he sends. I wonder what’s going through his head.
