Should I stick around or move on?

Idk what to make of this. My ex bf and I started talking again a few months ago. He said he wanted to take things slow this time, which I totally agree with. It’s been 2.5 months of us being “friends” with benefits of course but we don’t label it that. Yesterday I asked him what we were and he said, things are going great but there are still a lot of things we need to work on. For example, I have trust issues because of our past. I don’t blow up on him nor do I demand anything though. And he has been making a huge effort but there are times I have caught him in little white lies, cause he thinks I’m gonna be upset although I’ve told him many times that I wouldn’t. Like I said, I don’t blow up on him and I’m not controlling. I think it’s cause of his past relationships. He did say yesterday that he could make a bigger effort and he will. Once in awhile he’ll ask me why I’m too nice to him and too perfect for him which kind of upset me yesterday because he made it sound like he’s not the right man for me. His close friends and family know about me but he doesn’t show me off like he did when we first dated, so for all I know, all his “admirers” which I know he has, don’t know about me. But other than that, things are great. He bought plane tickets for us to go on a mini vacation, at least twice a month he’ll take me somewhere expensive (ex: a brunch cruise). He doesn’t like me paying but sometimes he’ll let me pay for little things. I told him it’s 100/100. You got me, I got you. I’ve never had Disneyland passes (he has when he was a kid) and he says he’s going to get them for us 2 months after they reopen. But my best friend, has told me that he wants the benefits without the title and I should just move on, that it’s never gonna go no where. I need someone’s unbiased point of view.
