Do you trust your boyfriend

My boyfriend and I have been together for awhile and I want to trust him but he's hurt me in the past. I'm also insecure sometimes when I'm around other girls that look better than me, I know that's not healthy on a relationship but I can't help because I'm not really his type he usually goes afte. Am I overacting? Or being too jealous? Is the way I feel stupid he says it is..... 😢😢 idk how to fix how I feel
