Husband and wife not being intimate for two years

Q: I want to know the validity of marriage if the husband and wife didn't have intercourse for 2 years. The husband is unable to do it with his wife. They both consulted  a doctor and medicine were given but still the husband doesn't show much interest and he doesn't take the medicine. The wife on the other hand started to feel depressed and alone. What is the wife's right and what she should do?
