There had to be a reason why your relationship has hit a rough patch as of late. Whether it be your lack of attention to you wife's needs or various other circumstances, she is probably quite distant from you. To begin with, for you to be able to win your wife back, you need to be aware of what is predominantly most important to her so that you may maintain a sustainable and healthy relationship together.
First, grasping her needs. Them being your constant attention and undying love. As I'm sure you are already aware, women are far more sensitive than men when it comes to their feelings getting hurt.
There are a number of things which your wife needs to be sure of before she is able to take you back. One of those is your attitude towards the relationship. Are you willing to really give this your all? How stable you are to be with as a partner and so on. So you will want to be prepared to address each of these issues and put any lingering doubts she may have of you to bed, right from the start.
What is more convincing than simple words that pop out from your mouth? It's your actions (if sincere enough), that will drive your message of love and affection home to her. There won't be any mistaking it. There's a high chance that if you are not together, then she mightn't be fully aware of your real feelings about her.
This can be accomplished by sending her small, yet meaningful gift such as cards, flowers or even surprise her by picking her up from her work and treat her for a nice outing at a restaurant she really likes.
You must not forget to tell your wife that you love her with absolute certainty. It helps to combine with this the above suggestions and to make sure that you don't fall into the group of men who forget to do so and wonder why why their relationship is slowly starting to crumble.
It is wise that prior to winning your wife back, you reflect upon the things you might have said or done that played a part to the problems which eventuated. And take the necessary steps to make changes within yourself so that your renewed relationship will have the a strong chance of succeeding.
Being able to make the necessary changes within yourself is vital for your relationship to stand any chance of growth. If you can't be sure if you are able to do it, then pursuing your wife mightn't be the best idea. Because you will likely just end up with the same ill feelings once more.
Please understand that if you don't have absolute commitment towards loving your spouse, it just won't work. Therefore, you may have to make some small sacrifices such as more time away from work, so that she gets your undying attention.
