Sharing Our Innermost Thoughts

i wanna share something …and that is about my relationship . So we broke up a week ago just because I was more involved in this relationship and i wanted to focus on myself , he never cared about me and he didn’t even had feelings for me …so we broke up …after that , the next day we were like so quite and not talking to each other …a few days passed and he started behaving like suddenly he cares a lot …when we were in relationship he never texted me …i was the one who texted first and now after breakup he text me almost every second day for random things like how much I have studied , am i coming next day to class , etc etc …after classes he asks me to wait for him so that we can go home together , in classes he saves seat for me and ask me to sit next to him …like why man …now what you want …if he’s like to be friends with me then this is not a friendship but i think it’s going beyond that …and on Monday what happened was that we were walking together to the bus stop and laughing at random things , it was so different that day that I can’t explain in words …it was like we both were in crowd but nobody was there …we were walking , he was like - walk slowly , we’ll sit somewhere and talk for a while …you know i am a kind of person who have nothing to share and he was also like that but nowadays he’s like sharing everything with me , each and every small thing which he never used to do …so i was talking about that day …then we reached the bus stop and he was saying something about hands i don’t remember exactly but after that he was holding my hand and we both were in public but still holding hands , for the first time he was not afraid to hold my hand in public otherwise he never did this before …it was so romantic , we were looking into each other’s eyes , laughing at anything , holding hands and his bus came but he said that you’ll be alone so I’ll go in next bus …he was actually behaving so nice that I’m confused what he wants now …and after that day when we met he called me before meeting that he’s waiting for me, for the class and then we were walking on the road i was walking like I don’t care about anything and he said nothing but he himself started walking on the side of the road and got me to the other side …he was like so protective that time …idk what’s this happening …why is he behaving like this after breakup …when we were in relationship then he never cared and now …Idk what should I do …what’s this happening idk …why it’s happening idk …
