Playfully mocking your partner is one thing, but if your partner is continuously humiliating you for various habits, they may be trying to control you.
If chastised enough, you may try to change and conform to their expectations. It's hazardous to shame someone because they may start doubting themselves.
Comparison is another red indicator. Many manipulative partners openly compare their S.O. to others, including their ex.
This is done to make you feel inferior or to make you work harder for them.
It's manipulation when your partner wants to know every detail about where you're going and who you're with and gets irritated if they don't. It ultimately establishes authority over a spouse.
It's hard to admit fault, but if your partner is continuously blaming others, be skeptical.
Instead of stating, "OK, you're right, I didn't handle that as well as I could," manipulative people will try to defend their actions and convince you that they are right and others are wrong.
Every couple disputes, but a deceitful partner may triangulate to make every conflict your fault.
This is when someone tries to get friends, family, couples therapists, or independent third parties on their "side" to prove they're correct.
