My husband fell in love with a married female customer.

Hi Ma,  I am a lady of 33 years old and got married at the age of 18 years to my husband but I just discovered recently that he has fallen in love with one of his married woman customer which he said that she is his friend not his lover but sincerely speaking ma these two love birds can not stay a day without calling or chatting in the social media even in the middle of the night. 
My husband on the other hand deletes the messages she sends to him immediately they are done, he also deleted her contact from the call log also after calling her or receiving call from her. 
The woman usually send her pictures to him with the some inscriptions like ' I wish am with you, missing you, let me be the one that will bring you happiness, etc' . 
And this woman is gradually taken the love of my husband away from me because both of them now have an unhealthy emotional attachment. 
Please ma I want you and your fans to advise me on how to get my man back to myself.

Dear sender, 
When a strange woman decides to meddle with what doesn't belong to her, a provoked wife will fight a fight of faith. 
It's time you sit your husband down and tell him how you feel about his attachment to that lady. 
You won't stop there, you would also get down on your knees and pray and pray and leave everything to God who can transform your husband. 
When you pray, make sure he is awake or around and he hears your prayers. 
Not so that he gets scared but so that he would realise that you do not need to reduce yourself to having anything to do with the strange woman. 
Keep on being your best in your home and do not deprive him of his conjugal needs. 
Don't just keep quiet, it is not ordinary and you shouldn't treat it with levity. 
If there be anything he wishes to let you know, do well to listen but don't relent in seeking the face of God over this. 
With prayers, love, patience and understanding I know you shall win the love of your husband to you and your family.
