Communication style driving me mad

[Overthinkingeverythingallthetime]

I recently returned to old after a loooong break away. Matched with a lovely guy & we have met 3 times now. I really like him. We have lots in common & talk & laugh a lot when we're together. The issue for me is his communication. I know we've just met & are not exclusive, although I'm not seeing anyone else til I see how this turns out. Sometimes he will message me a lot & then other times seems to ignore my messages even though he's been online. Is this a red flag? I know I'm an overthinker so just looking for some perspective...

It’s not really a red flag. We all go through busy and less busy periods. Considering some of the men I met online before meeting my husband (not online, through a friend) he’s not a red flag yet. It’s really hard to date someone when you don’t have friends or even co-workers in common. They always seem suspicious, in my experience.
