Is this a red flag?

My friend started acting extra friendly 5 weeks a ago, I told him at the beginning that I got out of a bad relationship so i wasn't looking to date anyone at the moment, He clearly knew i was drunk when a few nights ago he asked me out. VERY drunk me agreed,
But as someone who i thought was responsible why would he do that? Number too he literally love bombed me and we have a few mutual friends in our inner So he repeats so many times , don't tell anyone we talk. I'm taken back because one i would never because it's not even serious, but why would he keep love bombing me to , turn around and say don't tell anyone we talk (mind you repeatedly)🤷‍♀️🤷‍♀️
