so I really need some advice

So I have had a history of terrible relationships my whole life. I've been cheated on, mentally abused, and then severely physically abused to the point I still have an active protective order 2 years later. My boyfriend now is different than anyone I've ever dated. He's sweet, communicates, reassures me, constantly does little things here and there to remind me he loves me. And let's me look through his phone when I'm feeling insecure. But I'm scared I'm going to end up pushing him away eventually because of the trust issues I still have from past relationships. And I was single for over a year before I met him so it's not like I rushed into another relationship either.I just can't shake these feelings off. Does anyone have any tips to help? Because I don't want to take it out on him.
