past relationship is still affecting me

so a couple years ago i was on & off for 3 years with this guy who was horrible to me. he raped me when i was 14 and i didn’t tell anyone about it for years. he also always turned everything around on me and made me feel crazy for talking about my feelings or anything to do with me and would make me feel stupid for doing so. he was extremely toxic and i was dumb and thought he loved me but eventually i got the strength to leave him and now i’m dating this guy who’s really wonderful and i love him so much but every time a problem occurs and i have to talk about my feelings i start crying. he gets so frustrated with me and doesn’t get it, but i think maybe the reason i’m doing this is because i kept everything that happened inside for so long that maybe now it comes out when it comes time for me to talk about the things that upset me ? what do you all think . should i tell him
