It's one thing for a partner to poke fun at your habits now and then, but if they do it repeatedly, it could be a sign that they're trying to exert control over you.
If you get reprimanded severely enough, you could strive to alter your behavior to fit their standards. Shaming someone can be dangerous since it can cause them to doubt their own abilities.
A further warning sign is the act of comparison. Many manipulative partners openly evaluate their current or previous partners against others.
This is meant to put you down so that you would be more motivated to please them.
Manipulation occurs when one's spouse insists on knowing every detail of one's plans and becomes annoyed if one does not share such information. In the end, it cements one's position as the superior partner.
While it's understandable that neither of you wants to confess blame, you should be wary of a spouse who does so routinely.
Manipulative people, rather of admitting, "OK, you're right, I didn't handle that as well as I could," will instead try to justify their behavior and convince you that everyone else is in the wrong.
Every partnership has fights, but a dishonest spouse will try to pin them all on you.
This is when a person tries to convince another person that they are right by enlisting their "side" (those who agree with them).
