One trend that is toxic is that of women going on social media to bash and trash men. Complaining about their dating problems and then asserting that all the problems are because of men and couldn't possibly be them. This type of attitude in dating will bleed into your marriage if you manage to keep a man long enough to get to the alter. Being full of yourself is toxic.
Some of you women have your sex life backward. You're supposed to be hard to get when you're single and easy to get for your spouse.
