Wow, Sahirnee, you were really harsh!
The problem is, you were right on the money, and relatively succinct.
The bigger problem is that the OP probably won’t take up your advice because of the way it was delivered.
The even bigger problem is that the OP probably won’t take up anybody else’s advice (after all, it’s been pretty consistent) either.
THE REAL PROBLEM IS WITH THE PERSON WHO SUBMITTED THE ORIGINAL POST.
ARE YOU PAYING ATTENTION WALLSTREETJD?
The responses I’ve seen so far have come from people who seem to be taking the original post at face value – in other words, as a request for advice. The alternative, of course, is that it’s basically a troll to get kind-hearted people to respond, to give of themselves to a faceless stranger. [It will not solve the debate on whether or not altruism really exists, if that’s was this test was for.]
This same sob story has been presented across millions of fora in millions of languages – and a few dozen times here on the SD. It’s a classic soap opera plot. Those who respond are generally kind-hearted and offering advice for your benefit. We’ll never know if this one is real or just your way of gaining attention over the Internet.
So here’s the thing, WallStreetJD: The object of your affection has been cheating on her husband, cheated on her ‘mister’ with you, and will undoubtedly cheat on you given the right circumstances. If you really really love her, you’ll be burned **when **that happens. Several have noted that one of your less preferable options is to accept the role of second stringer and go back to being friends. Of course, if she cries on your shoulder and then starts rubbing your crotch…
GET A GRIP ON YOURSELF!
No! Not literally! Stop that!
You haven’t mentioned your own background here, but some have hinted at substance abuse or other abuse in this woman you love. What abuse have you endured that fostered the belief that you deserve no better than third string after the husband and mister?
Yes I’ve been there. Yes, it sucks. And the only way to get out of it is to just get out of it – physically, emotionally, financially, psychologically, geographically, whatever. Part of my therapy included literally leaving the country to clear my head. What really did the trick was finding someone else who was available AND made me feel all those wonderful things (and more) when we were together – and still feel them when we were apart.
So give yourself some credit. Break free and go find a relationship* that will give you more and end up being more fulfilling in the long run.
AND DON’T LOOK BACK.
HEY OTHER RESPONDERS: ENOUGH OF US HAVE GIVEN THE OP THE SAME ADVICE OVER AND OVER IN THIS THREAD ALONE.
I SUGGEST WE STEP BACK TO LET HIM EITHER FOLLOW THE ADVICE OR GET LOST. ARGUING WITH HIM IS A WASTE OF EFFORT.
—G!
*They say there’s a guy for every girl in the world – but then there’s a lot of lesbians and a lot of gay men so that narrows down the field to give hetero people better chances with someone who’s just right… 
Never try to teach a pig to sing.
It’s a waste of time.
And it annoys the pig.
