Boyfriend catching feelings

Today I was at my boyfriends house and he told me he wanted to be honest with me. He told me he’s been a bit confused lately and trying to figure out his feelings. I asked him if he has feelings for this female friend of his that he’s been spending a lot of time with recently. He said he’s liked her for a long time, since high school. But he said that he loves me and wants to be with me and whenever he thinks it over he comes back to realising that he’d rather be with me than anyone else.

I don’t know how to feel. Of course I’m glad he’s honest with me but I can’t help feeling not good enough. I am worried that he’s going to fall for her. I know they’re really good friends and I don’t want to get in the way of that strong friendship. He’s confused and it’s clearly tough for him to work this out but I don’t know what to do. Any advice?
