Since men don't like thin women should I gain weight?

I'm 4'8 and 96lbs. My boyfriend dumped me because not only he lied about not having another woman but he said he doesn't dig skinny chicks and he wants a REAL woman with meat on their bones to bang and men do not wanna date a bag of bones. I called him out and cut him out. Some women are wanting to put on weight because they hate being skinny and want curves and to be filled out.
