Does he just playing with me?

I have met this guy at online chatting starting from December 2019. At first I just ignore him because he take a few days to reply my text. So every time I just let him initiate first our conversation. After 3 months, he said to me that he wants serious relationship because he cannot forget about me. I told him that he always dissapeared but he just respond that he thought he will disturb me.

He is trying to convince me to believe and tell everything about his family, job, ex girlfriend and etc. He also said he doesnt want to waste him time to find another girl and he knew I was the right one to become his girlfriend. That time I was thinking that he is actually getting serious to know me more.

Day after day everything getting better and I started to like him. He always text me and calling me everyday just to tell what he actually doing for a days. I started to ignore all guy that want to get close with me. I knew he is the right one for me. After two weeks, he didnt reply and text me late. He was told me that sometimes he has some habit/feels to keep silent and doesnt want talk much to anyone especially thru mobile phone.

I was accept his reasons because I want to give him space. He come back again to me after a few hours/days/weeks. Sometimes I felt like he is losing interest to me or did he has another girlfriends. Or he just playing with me?
