My husband made me feel im inferior to his ex girlfriends and other girls. now i think i've developed inferiority complex. what should i do about it?

See details: You need to be honest and address these issues with your husband. Explain how his constant comparisons are destroying your relationship. If he continues then consider counseling preferably for both of you together or at least for you alone if he doesn't agree. Imo, this does not bode well for a long-lasting marriage.

Loving yourself: Learning to love yourself is an important skill. No one can actually "make" you less than you are, unless you allow them to. Why do you feel inferior to the ex-girlfriends? They are the ex- ones! he has moved on from them and has chosen to be with you. Try to remind yourself everyday what is good about yourself. If you keep having trouble with your self-esteem, see a good therapist.
