Leaving Him After 10 yrs

After 2 years of my babys father not being intimate with me despite my.efforts to initiate, with him not being able to forgive me for things in the past and holding grudges...Ive decided to tell him that I cant do this anymore. Its like hes holding onto me bcuz we have a child and bcuz of the love that we have for one another because we have been together so long and are used to eachother. After.coming to this conclusion everytime I see his face or I see him period it makes me sad because its been over 10 years and I will miss his face...I just feel like a roommate that he loves. Ive tried talking to him 3 times within these 2 years and promises are made but nothing changes.intimate wise. And I cant stop crying because I think of our 2 year old not having her dad there everyday, what about those days when she asks for her daddy or when she cries and only his hugs can soothe her...I feel so sad and my heart hurts
