I feel like most of the time when men call a woman "crazy", "psycho" and "insecure", 90% of the time there's a deeper seated issue. A lot of guys seem to think it's okay to call a woman crazy, after having stood her up or ignored her and neglected her all while saying "I love you". And they call a woman psycho after having put her through the worst anxiety of her life. They'll say she's insecure cause she asked, "why do you have to walk outside to see your text messages and answer phone calls in another room?". It's all fucked up. Too many good, kind and loving women being labeled and judged for things they're not, by bad men who say these things to deny their own behavior. Support women and give them the benefit of the doubt first before you believe what he's saying about her. Even your close guy friends have their secrets.
There are such good men out there, who wouldn't write off women like this. A good guy is understanding and speaks highly of women. And if he's saying these three words or saying "she's a bitch" of ALL his exes or women hes dating there's something up with him for sure.
