Should I stay with my sick girlfriend out of sympathy or leave her, move on and find a healthy woman who I can happily enjoy life with?

Hi all. I've been with my girlfriend for about 3 years. We live together and I'm her first boyfriend despite her being 33. She always tells me no other guys wanted to date her because of her health situation. I feel sorry for her. The truth is I love her as a friend but I'm not in love with her anymore. She has type 1 diabetes and her condition just gets in the way of not just her life but my life too. I have to take her to doctors constantly and sometimes pay lots of money for co-pays. She sometimes wants me to eat what she eats because she's diet limited. I'm always worried about her health. She talks about how she wants to marry me and have kids one day. But deep down, I don't want to marry her or have kids with her. I really want a healthy, wild woman. We're not married and don't have any kids. We haven't had sex in over a year. I'm just tired of it. We're in our early 30s. Her parents expect me to marry her. I feel like I'm missing out on a full life when I don't have to. There's many women I know who want to be with me. I'm worried that if I break up with her and kick her out of my house that she'll go into a deep depression and her family will forever hate me. But I have a life and want to be happy too. What should I do in your opinion? Stay with her or leave her? Thanks.
