@shordeel87,
Ask yourself what you fight about "a lot". I imagine it's not one thing but quite a few things.
8 months, is still infant stages in a relationship and after 5, you moved in together, (nothing wrong with that) however, at least 12hrs a day, you are together and I believe he is trying to state that to you, you don't need the constant text messages and love you's daily he lives with you.
Anxiety is something that really needs to be helped with, more than likely it's your anxiety that is "needy" and needs feeding but in the end, you are going to push him away. Chill a bit, leave the conversations to when you are together, something to talk about, want him to show you love? Chill a bit, give him a hug when he walks in the door.
