Boyfriend advice?

So me and my boyfriend have known each other for a year and it’s a good relationship, my ex messed me up so I have trust issues sometimes with my anxiety bc I get into my head, I do trust my boyfriend just sometimes I overthink, about a week ago he said feels unwanted unappreciated and everything he does doesn’t seem good enough. Which is not true at all and I try to show him how much he means to me but maybe I’m not doing enough? I don’t want him to feel like that so what can I do to make this better and have him feel appreciated
