Red flags in men

31F here. Dating and looking for my husband. What were some red flags you saw in men in the early stages of dating (first, second, third dates etc.) that maybe you ignored or didn’t see at the time that ended up biting you in the ass?

Personally I pay close attention to a man’s dating history (especially if he’s in his 40s) and has not been able to commit due to superficial reasons (i.e. something was missing) or if they say they have never been in love…
