Anong thought process sa mga lalaking ganito?

So basically after long months of trying to fix the relationship and waiting for him, I gave up on my ex situationship after seeing him entertaining another girl during a party. I argued and cried to him when it was happening and in the end I ended up saying “you know what. Do whatever you want. Fuck it and fuck all of this. I am done.”

After that incident I decided not to speak to him. For some reason I haven’t blocked him on any of my socials. I just left things as is and went silent. We didn’t not speak for a solid month. No contact at all. However, on the second month of no contact, I started to post stories on ig again and sometimes repost stuff on facebook, to which he either reacts, replies, or likes my post. The reacts/likes weren’t consistent but he does it on most of my posts. I don’t really respond or mind it for the sake of peace of mind. However, I do respond when he asks about work and dates for deadlines. Our conversation are very short. Like 3-6 bubbles max.

Which makes me wonder. Anong thought process sa galawan ng mga lalaking ganto? They reject a woman who was willing to support and move mountains for them. Entertain multiple women during and after the “break up”. Why do they still contact them after knowing na masakit ang ginawa nila. May feelings pa yung babae sa kanya and she’s trying to heal from all that bs.

Like help me understand it. Probably my mistake for not blocking, ngl it is hard for me to block pa naman. But yeah, help me understand bakit mag message or contact pa yung taong ganto.
