I don't want to give up!

It has been a month since my partner and I started to be on a break and 3 weeks since my partner blocked me on social media. And I am not 100% sure if he is cheating, because it is just a suspicion I have had for the past week and half. Do you think it would be appropriate, if I showed up at his job (restaurant) with flowers and a monster energy drink (which he loves), to surprise him? We haven't seen each other since March due to Covid-19 and their reason for going on a break was he said he is dealing with a lot of stress, losing two friends to suicide and it built up in their head and it became overwhelming, I'm guessing. (I know mental illness runs in his family, not sure if that is helpful information)

We have been dating for a year and few months now. He means the world to me and I really do not want to lose him. 

What should I do?
