My ex randomly texted me?

So I’m ex and I have had a rollercoaster of a relationship it’s honestly embarrassing. He clearly has issues he was verbally and physically abusive. Both sides of our family know. He’s just a very insecure man but we started out as friends for many years prior. I didn’t realize he had this other side to him until it was too late and I got out. I’ve been broken up with him for about a year, we were together for two and he basically lived in my apartment 24/7 we were with eachother all the time, then to nothing. We had a convo and agreed to remain friends (whatever that means) and unfortunately I have had crash out moments recently where I slipped up would text him about something stupid in my life, he would always reply but it’s obviously not what it used to be. So then I get upset and down. (That’s on me). I was told in therapy it’s a part of the grieving process. So I decided to stop as of 3 weeks ago have not crashed out and hit him up and yesterday he texts me hi how are you. I took 4 hours to respond bc I was busy but I wasn’t expecting to see his name at all it’s been a while and it’s just minimal responses and it goes dry. Why do men do this? Like what the actual hell? it was the day after Valentine’s too aka yesterday so I just don’t understand why he would hit me up randomly if he purposely was trying to make the conversation go no where. Once I responded hours later he just kept being dry and I was over it. Is this like a narcissistic trait? or does he actually miss me/ was he genuinely thinking about me? It’s so messed up and confusing and now i feel upset that I responded just to have zero actual convo. I really just am trying to understand and grasp what he was trying to accomplish or do because I genuinely will always still love him so I don’t mind having a civil conversation but he keeps making it bland and so hard but he hit me up first outta nowhere. What is going on in his mind? I need opinions from men mostly. Thankyou!
