Cancer Man Ignoring Me

I started seeing this cancer man about 3 weeks ago. When we first met it was like instant connection. We further communicated through text over 2 full days and met up 3 more times the week after. He said he was already very emotionally attached towards me. I went overseas with my friends shortly after and he was not happy about me sharing room with a group of friends that includes opposite gender citing "Traditional Values of Female Modesty". Despite me hitting one of his major "dealbreaker, we will wanted to be together and we went out again and was intimate. After that date he suggested to meet parents and pull finances together, which I appeared lukewarm and he seem to start to put me on a emotional rollercoaster. He started accusing me but refuse to tell me what I did that made him hurt or sad. Then he asked for a breakup via text saying he cannot give me what I want, but soon he uturned back and texted he love me and can accept me despite that I did things "behind his back" and "wasn't opening sharing my emotions and thoughts". I didn't know how to deal with this so I went on a 5 days self healing trip where i ignored him and told him to think about what he did to me and to become a better person. He was really uncomfortable i went away and sent me texts everyday. I didn't reply until he started accusing me of seeing other people and I should tell him so that he can move on. I replied to tell him I still want to be with him and that calmed him down. I even asked if he would pick me up from the airport the next day which he expressed he wanted. But the next day came and he was not at the airport when I landed. He didn't even read my msgs, so i deleted some of them. When he finally saw, instead of apologising for his absence, he started to accuse me of doing things behind his back like deleting my messages. Yesterday he texted Take care and Bye, before going NC on me until the night where the messaged I Love You in response to all my replies. I sent him tons of messages but he read and doesn't reply anymore.

I know its a common thing for cancer to be flaky and retreat back into his shell. but i don't know what to do now.
