Illicit relationship is a big problems and you need to be very careful in how you manage your relationship. Using force or behaving in a irrational manner will not help you in any way. Behaving maturely is the way forward. Whenever there is illicit relationship it is because the horoscopes of husband and wife are weak and therefore the person is attracted outside of marriage.
First and foremost you need to do things that will strengthen your relationship. These include astro remedies and also some change in your nature. Your horoscope has Mars in lagna which means that you also have strong ego, you are hasty in taking decisions, you say things in haste without thinking first. You get provoked easily.
Change this nature of yours if you want to strengthen your relationship.
You can also keep fast on Mondays. Offer Jal to the Shivling every Monday morning.
You can also do the remedy given below.
Take some Kumkum (Vermillion) and spend on the bedside of your bedroom , where the husband sleep. In the morning after bath apply that Kumkum in your maang while taking the name of Maa Parvati. Do this on Sundays and on Mondays visit Shiv temple as suggested above. You will see good results. Also change your nature and you will see vast improvement in your relationship.
