Taking my heart back

Me and my fiance been together over a year we have a 7 month old daughter and knew each other since childhood. Well at first he loved me so much I never felt love like that now he keeps disrespecting me taking my love for granted and thinks our life is a game. I love him but am just burned out. I been thru to much in this life and I am to old. Every part of me wants to leave cause I truly feel he's not going to change and I am not going to allow him to treat me any type of way. He keeps blaming me like y do I want to break our family apart. I told him we don't get along and your so ugly to me it's not healthy for me or our daughter. So idk anymore I just want to take my daughter and go somewhere safe and peaceful. Should I keep holding on hoping he realizes this is no joke or just leave. So confused and numb.I just want to b happy again. If he continues I am out.
