It’s normal! It happens with everyone and even with me when my best friend praises my husband in front of me.
Jealousy is a fun part of every relationship and instances of jealousy are normal as it shows your unconditional love for your partner and how much you care for him. But, don’t make it your habit as jealousy can also lead to mistrust or insecurities. And remember one thing, there is a fine line between jealousy and possessiveness and possessiveness is definitely not healthy for your happy married life.
You might have an inferiority complex which may make you feel jealous all the time when someone praises your husband. You can’t stop everybody from expressing their feelings. So, shed your insecurities and remember one thing that he has chosen you over other women in the world. You should try to overcome your fears, heal your insecurities, and have faith in your partner and your valuable relationship.
