Advice😕

My boyfriend and me have been dating for a little while and we used to text all day everyday and hangout almost everyday as well.

Now i never get a reply from him and like he usually never hangouts with me unless I make the plans first and then I have to remind him over and over again. And like I have to text him 24/7 if I want to talk to him

If I don’t text him first he doesn’t reply for hours. He leaves me on read.

And now I’m honestly just feeling really lonely. Really hoping I get to at least see him for my birthday in a few days 😞 it just feels like I’m a bother

Advice for what I should do?
