ANSWER:
You must weigh the pros and cons of your decision wisely as you will be the only one who will suffer its consequences. You must not let shaytan destroy your marriage like this. So many women who opt for divorce only wish they hadn’t when they are left with no one to support them financially, and they are old and alone, while their ex lives a happily married life and moves on!
Try to be the one he seeks his tranquility in by creating a positive and loving atmosphere for him so that he prefers spending more time with you and takes interest in you again. 39 is not old for a woman and you shouldn’t let his words enter your heart or have an impact on you. Ignore such words as if you wanted, you can say the same about him. Leave that for the sake of Allah and He will reward you for that.
