Why does my ex barely communicate but gets mad if I dont?

He checks in every day with "morning" and "u ok" texts. If I don't reply within minutes he's asking what I'm doing, who am I with and presuming I'm with a guy. BUT when I do text with him I feel like I'm making so much effort. Talking about my day and stuff. And he just responds with lol and yh and haha. It's such a one sided convo. I can poor my heart out one minute and just get a lol. Or a "OK kl". But when I reply short like if he say "u ok" and ill say "fine. U?" He is like wtf? Fine? Wow. And if I say why we still talking or say there's not much point us talking he says why?

I just told him hey let's check in once a week unless we got something interesting to sat. And now he is like wtf, why u being like this?

Why does he hardly respond yet cares so much if I don't! Urgh!
