What does it mean when my ex says ‘I love you, I guess’ to me?

My ex-boyfriend and I started talking again a little over a month ago after being broken up for seven months and also being no contact.

From the start, he told me that he loved me, but doesn’t wanna be in a relationship with me when we first reconnected and that we can only be friends.

Which I never believed in the friendship thing.

Fast-forward to now , when I told him I love him he said I love you , I guess.

We are not officially back together.
