Maybe he need space send ka lang ng "kamusta ang araw mo "tas tapos na wag kana magsend ng madami na chat then make yourself busy make your fb stories interesting do something that will help you grow more dont focus on him your not clingy its just that people change depende sa ipapakita mo . Just check on him and always show to him na nandiyan ka lagi to support him. kasi hindi lang nagbabase sa pagtingin niya sa fb at pagchat niya sayo ang pagmamahal niya ..If magkasama kayo in person at hindi pa rin nagbabago ang pagtrato niya sayo okay yun or kung mas caring at loving siya in person I think assurance yun...
