trust

alright so i am in the best relationship i’ve ever been in. he wants me for more then just my body and actually makes me happy. but previously i was in a toxic relationship. i was cheated on and emotionally and sexually manipulated. i know i can trust this guy to not cheat on me but there’s always something in the back of my mind saying what if i’m not good enough and he finds someone better. any tips on how to get these thoughts out of my head?
