toxic relationship

my ex and i weren't good for each other. we fed on each other's insecurities. i fed on his jealousy as i've not been sought after and he fed on the anxiety of me not wanting other guys. he of course was more brazed with his jealousy as 2 of the guys he didn't know and worried i'd like them more than him. luckily we got out of that relationship. he knew my secrets and weaknesses and fed on that. i'm still a tad embarrassed about 1 secret he knew but i'm slowly coming around to telling people like i'm coming around to the idea that boys can (and do) like me.
