Although you don’t have the karma for your relationship to be beneficial, the fact that you are together indicates that you have some previous karma to deal with. You are now married to a person who was created by your delusions and karma. You are married to the result of your own delusion and karma.

The solution is to change the circumstances so that the relationship ends harmoniously. You should make prayers for your husband to find another woman who he is attracted to, and who will benefit his mind. This way he will leave with a happy mind, and the separation will be harmonious. When the prayers are made with the motivation for the most beneficial outcome, then there will naturally be more power to the prayers.

For this, you need to purify the previous karma with your husband, and make prayers for him to find a suitable partner. Until the karma is purified, there will be difficulties to experience.
