Relationship advice

I have trust issues, always have had them, the guys I've known haven't mean very good to me, a lot of my sexual relationships with guys have been toxic, I guess you could say I have never been good at picking them. My last relationship consisted of a lot of emotional abuse and he sexually assaulted me a lot of times and I thought it was fine and didn't realize it wasn't right but I knew it wasn't really right and it continued to mess me up and still does. I've found someone who's so so good to me, so kind and loving, understands that if I don't want to do something it's okay and he lets it go and it's not a big deal and doesn't pressure me or guilt trip me or stick his dick in my mouth and then tell me later I'm worth nothing without him, he makes me so happy, and the trust issues I had before didn't get as bad until my last relationship. But I'm happy with this guy and he's the best thing that's happened to me and is considerate and caring and I'm always waiting for the other shoe to drop but it doesn't... I just don't know how to get past this feeling I love him and do trust him physically and emotionally which is what terrifies me, it hasn't happened a lot before and I've always felt a bit unsafe and very unsafe since the previous relationship. I just don't know how to get past this, I'm happy but also scared and always scared he's gonna hurt me some how but I know deep down he won't because he's so gentle but that fear is always gonna be there, and it's just upsetting, I don't know how to be okay in a good, healthy and happy relationship. Any advice would be greatly appreciated 🙏🏻
