Not hearing me

What do you do when you feel like you keep repeating yourself, you keep expressing how his actions make you feel, how you feel neglected, and not much of a connection yet the behavior doesn't change. Changes for maybe a few days but ends up right back to where the problem started. I feel myself pulling away, im done begging for my needs to be met, but i also know that marriage is hard and that i love him and that the grass isn't always greener but I also am scared of my thoughts.
