Advice

I have been with my partner for almost 5 years. We used to have sex every night when we first got together then her cancer came back so I knew she wouldn't be interested in sex so I didn't ask for it. We went a while without sex while she had chemo but now it's been almost 2 years since then and she barely acts like she is in to me. We got married she says she loves me but everytime I try to kiss her she just gives me a peck, when I try to plan things we go do them like movies and out to eat but we barely have sex like seriously it's been like 3/4 months. And it's like that all the time until I start botching that I want to have sex then she says ok well we will tomorrow and then we do but it's like she isn't into when we do have sex. Mind you we are both women, we get along fine and go out to do things together but o just feel like she isn't in to me anymore and o don't know if I should keep going down this road feeling like I'm in love by myself or move on in my life. This has been going on for 2 years now. When o talk to her about it she says of I didn't love you or want to be with you I wouldn't be with you.
