Its definitely a red flag if a man acts like that. But not only is it not bad,its neccessary if its your woman. A woman should be secure about everything involving you,except for the fact she cant possibly lose you.
Its like the fear of death,is a little fear of death a bad thing? Or does it keep people aware,and from doing stupid things? Now a completely irrational fear of death is a different story,and liable to cause problems.
It's a red flag for anyone. The part you're not focusing on is the constantly part. That is not healthy for anyone.
That means she's going to make that mans life a living hell to due her insecurities. Stop and actually think about that, especially if that man hasn't given her a single reason to be insecure. That's not fair to him or their relationship. Having to constantly reassure someone about something constantly will eventually cause them to leave.
Again, this is not some ego "oh she needs me" braggadocios thing to be proud of. Essentially her mental issues will eventually affect him mentally, sir that is not okay. After that relationship he'll have to "unlearn" the bs he had to "learn" to "keep her happy" which he could never do in the first place. If someone needs constant reassurance, I need the person doing the reassuring to understand they'll be doing that forever unless the other person gets help for their issues or they break up. I hope you never experience it because it's mentally exhausting
Edit- Case in point, the post above mine, who wants to constantly do that? Every day, every phone call, every text message, every interaction with the opposite sex etc? I'd rather be single than do that bs
