Simple friendship jealousy can become controlling behavior if nobody addresses it. You might notice a friend feeling envious of your success or worried about being left out. These toxic traits can turn
jealousy into possessiveness, and they might try to dominate your relationship.
Watch out if your friend gets upset when you hang out with others. They might make nasty comments about your other friendships or act like you should put them above everyone else. Some friends try to cut you off from others by making you feel guilty.
This controlling behavior shows up as constant criticism, disrespect of your feelings, and attempts to shake your confidence. Some friends might even try to sabotage your happiness because they're jealous.
These patterns—manipulation, codependency, and controlling behavior—create friendships that exhaust you instead of lifting you up. Spotting these patterns early helps you deal with toxic dynamics before they cause serious emotional harm.
