advice????

so my boyfriend and i have been dating for 4 months, but we’ve been best friends for 2 years and he told me he loved me almost a full year ago. it took me a long time to accept it, but i know he’s my soulmate and i love him more than anything. he makes me so proud to be myself and loves me for who i am, despite all of my flaws.

i love him so much, but i always find myself getting really down about his past and other girls he has hooked up with, and all of these were way before we started dating. even now, when we bring up some of my friends or something small where he says he touched a girl’s ass or something insanely small, i get this horrible feeling in my gut. i know that in reality we both have pasta and he feels the same way about people in my past, but is there anything i can do to help myself feel better about this????
