What should I do when a cancer man disappear?

I am a pisces girl and I met a cancer man from England. We met when we were traveling, he is friend of mine. I didn't expected that we could have memories because first time I just keep the circle of friend. I keep traveling and he also and once when I am back the same city that we met first time I asked him to hangout with other friends. And this is the time that he said he like me. I was really drunk and he taken care of me.. I know one of my best friend like him so much and wanted to sleep with him but when I am drunk I still remember that he held my hand and told me that he like me than my friend. Next day after woke up I texted him then he said I was really funny that night and he asked me to meet up just me and him. Then I met him without tell my friend. And we ended up on the bed. Next day he went to Sri Lanka like 2 weeks and I don't think we will meet again. Then I got job in there so I am still there, been 3 weeks without him and he is back to those city again and we met.

First time we went out in public he seems doesn't want to get closer with me but when we walked in quite way he tried to hold my hand and being sweet. But day by day we are getting closer and when I saw him talked with other girls he can feel that I felt insecure and he seems can read my mind. I can't explain everything but I will make it short...
He went to small island and still keep in touch every time he is keep moving always back to me and came to see me. Also last time when we have to back to our hometown we spent all day together, he told me about his parents, family, brother, his mom and his old pictures, also his pics when he went to some places.

We still keep in touch until he got home and that is the last time he message me. I replied him directly but he didn't replay yet it's been 3 weeks. I think maybe I was scared him because I talked like he is my boyfriend and he keep said to me that he doesn't want a relationship. But after one message I sent him message want to say happy birthday he is saw my messages very fast. But still no replay. When I was hangout with him he never look at his phone also when he got messages he never open it. I just have no idea what should I do? I tried to forget him.. I tried to date with other nice guys but I always sad and wanted to cry but I can't because no one like him.. he is the one make me felt secure and know what I want to make me feel safe. I miss him so much.

IDK Maybe he has a girlfriend back at home. Doesn't sound like you two had a deep connection. Just sex. If he was interested in you, he would contact you and be consistent. Clearly he is not.

He was consistent contacted me also from snapchat but last time I lost contact because got trouble with my snapchat so I didn't replay him back. But he doesn't try to find me out after
