I need adviceee

So I been seeing this guy for a bout 9 months now. Up until a month ago everything was fine I'd see him like nearly everyday we'd do things he'd talk to me all the time, checking up on me and that.

He was pretty quick to tell me he has feelings for me and told me quite often. And I've told him I feel the same way.

But recently he has switched up on me without any explanation or anything. I feel hurt and confused. He has told me not the take it personal. But I can't help it. He has stopped messaging or calling me only messages if I message first and takes ages to do so.

I have tried telling him how I feel but he finds away to switch it on me 😩 I told him to stop f*cking with my head

I have feelings for him and I don't want nobody else. It's just hurtful and frustrating that he has switched up without an explanation. I haven't seen him directly in about three weeks and haven't spoke in about four days as I refuse to keep messaging cause i don't want to seem desperate for him or come across as a pest.

Please comment what I should do, do you think i should still Persue him or leave it all out. Xxxx
