Take it from a guy, that has been in the same situation. Let her go. Your wife or at least your son, are your first obligation. Girlfriends come and go. Family is forever...

Family is forever. It was your responsiblity right from the start. From the day u walked down the aisle with your wife and the day you witnessed the birth of your son. Let that woman go, it's only lust/infatuation.

I agree family is forever and no one can take that away from u. Be a man and accept your responsibilities. You think u love her, you think you can't live w/o her...you think she will make you happy. You want to build a new life w/ her. You might think all that now but when u're all alone you'll live to regret it. People want what they can't have..Don't take what you already have for granted. Don't make that mistake of thinking that there's something better out there for u.

I don't believe enough of the story has been told to advise you on the situation that is before. It's kind of too late to tell you that family is first considering that you have already put your pleasures before your wife and child. All I can say is think of what there is to gain and what there is to lose. Your wife has been there for 15 years plus has bored you a child. And your son, how will he be effected? Sometimes we think the gr*ss is greener on the other side until we make to the other side. Some months of enjoyment with this young girl can't be compared to 15 years of love. Maybe things are ruff between you and your wife right now, but joy and pain is all a part of love. However, I don't know the whole story. My advise is to examine the situation carefully. Note your priorities and line them up in their proper place. Think of your vows you made with your wife and your obligation you have with your son. Then, ask yourself if this girl is worth leaving yourself. She might be a nice girl, don't get me wrong. But is this enjoyment with this girl really enough? Is it worth the divorce? Or can you do more to save your marriage? This is a choice you must make to began healing and restoration.

I agree with all the comments above.. Family is forever. Do the right thing, for her and your family. Let her find true happiness. She won't be truly happy if she has to share you with your family. Letting someone go is the best way of showing your love. Don't destroy the family that you've built for just one woman. She may leave you if she got tired of the situation, but not your family, they will stick with you no matter what.

Get real! Your wife and son come first. Grow up and get control of your emotions.
