Need advice from (May) Taurus males only.

I am a taurus female who is with taurus male since 3 years. It’s been 4 months he is doing push and pull without any proper reason , we did not have any break up etc. he blocks and unblocks me , when he unblocks we are on same page as we were , with all love. Nothing bitter. Then he blocks again. I reached him with multiple numbers he just says that give me some time.

What should I exactly do now to make him open up ? Whoever helps me sincerely may God help him with his wishes and desires. ♥️🌹
