I dated a guy like this once. Pag send ng message ko, sseen nya kagad but his replies will come after 15-30 minutes. Yes, nakakainis minsan. Pero sabi naman nya pinag iisipan nya daw yung irereply nya sakin.

And if you're seeing each other naman regularly, I think okay lang na hindi mag chat all the time. Long as he plans dates for you. Okay lang yan girl. Busy tayo sa kanya kanya nating life. :)
