How to stop thinking that he would come back?

I met a guy through reddit and at first I wasnt attracted to him but after sometime I actually liked him. He was into me to. We both vibed and we were quite alike. After a month of talking to eachother I told the guy to meet me and also cleared to him that I am not looking for a relationship but Marraige. He agreed and said that he will involve his parents first then he will meet me. Well he met his mom and talked about me. His mom rejected me and said that he should be in a relationship with me but on the side look for better options. I told him that mother's do such sort of things and she will agree just give her some time. He told me he knows his mom and even if she agrees there will be hurdles in future so it will be difficult so we should end this.

I told him that atleast we should meet then we can decide. He said there is no future for us and therefore we should not meet.

After some weeks I messaged him again to see how he is and he told me he wants to take me out and that he will talk to his mom again and there is some hope because his sister really likes me. We had a really good Convo for 2 to 3 days in which he told me it is so hard for him to move on.

Now suddenly out of the blue I am ghosted for 5 days. I messaged him and he saw my texts but there wasn't a reply.

I miss him and there was this bond between us which I haven't felt with anyone. I don't know what to do.

I want him to communicate with me but he isn't replying. I am hurt.

Is it so easy to give up? Makes me feel I am not worth the efforts
