I love my husband very much. We have been together for 30 years, married for 26. Since I was diagnosed with breast cancer in 2007, my libido has been in decline. Then, two-and-a-half years ago I was diagnosed with metastatic breast cancer in my liver and I am about to start a sixth course of chemotherapy this week. My libido has been zero since 2012. I worry about neglecting my husband as we are only 49 and 50. It is not his fidelity that concerns me, more that he is young to be widowed and obviously has natural needs, and I feel I am letting him down.
