Bases on this thread and the one you posted about your boyfriend commenting on your body it really sounds like you are in a relationship that is not healthy for you.

A healthy partner accepts you as you are and doesn’t body shame you or tear you down. A healthy partner looks for the good in you.

In my heart I kind of feel that you are mistaking insecurity for jealousy. You worry that he’s flirting with other women and that somehow you are not good enough and that he’s going to look elsewhere.

If you were calm a secure in your own self and body you maybe think along the lines of “he wants to be with other women? Pffft his loss. Plenty more fish in the sea.”
