Should I tell my bf abt a guy I started talking to when my bf and I were broken up for 11 days??

My boyfriend and I broke up on March 30th and patched up Apr 10th..we had been together for 6mnths then, but during the time we were broken up, I talked for 2-3 days to a guy who I saw abt 1.5 yrs ago at a class and thought was cute. We had little eye contact and he told my best guy friend that he had a crush on me. I was lonely and wanted to feel btr abt myself so I asked my best friend to ask that guy to text me. I nvr felt while talking to him what I did since the first day I started talking to my bf..my bf is the absolute love of my life and ik he really loves me back and so I feel bad that I talked to another guy within those 11 days of the brk up. I stopped talking to that guy the day my bf gave me a hint he wanted to patch up and luckily we did 2 days later. I still sometimes feel bad abt what I did. Should I tell my boyfriend abt it?
