What do I do?

Nothing, absolutely nothing.

You are married. (Is he?) You are off limits to him as he is to you. Avoid being alone with him or having any kind of intimate communication. That means no phone calls and no texting.

Be honorable and respect your marriage vows.

what do i do?

Sarah,

Don't do anything! Leave this alone!

I feel very bad for your Husband.

OMG I can only imagine what is going through your mind. BUT you have GOT to get your head back in tune with reality. Don't you dare do anything to cause your "oath" or personal vows to be rendered useless in your OWN sight. I am being very hard and critical of this as an opinion because it is deserving.

Who will you be tomorrow? Who will you be the day after? For starters, you will not be the very same woman who made a vow for better or worse.. In fact your vows will become useless. And that is about as useless as tits on a boar hog.

The question you need to ask yourself is: Who am I, and Why the hell was I even THINKING about infidelity?

And not to mention you will need to eventually disclose this to your husband. So make your bed, and get comfortable.

How do you know you are 'in love' with him. Have you been seeing him, meeting up, having a relationship, sexual or otherwise? Texting, phone calls, email?

What do you mean in addition to feeling very strongly about this man.

Why do you call it 'love'. What's been going on.

Do marriage vows mean nothing anymore? Maybe this is why the divorce rate is 54%. :(

You're married. If you didn't want to be married, if you wanted to be available to play the field, you shouldn't have gotten married.

Work on your marriage, you're no longer available, other men are off limits, you made a commitment to one man and one man only.

What is love really? Is it just lust? Tell us more about how you feel about him?

Anyway just like the others, don't do anything and work on your marriage instead.

Under what circumstances did you fall in love with this man? Is this a full blown affair or perhaps just infatuation from a distance?
I suppose in the end it really doesn't matter since you are focusing on another man and not your husband. In which case , like all the other posters said, you have the responsibility to be working on your marriage. OK, granted, you haven't described what your marriage is like but, still, YOUR MARRIED!
It never fails to surprise me how easily some people can just throw their values out the window when they think something better has or will come along. Oh, it's too hard to work out all the problems in my current marriage/relationship... sooo much easier to just move on to someone new! And ( here's the kicker) I deserve better!
Right now I think your husband deserves better.
You should be or should have been working on your marriage, not opening yourself up to your husbands best friend( of all people).
Why do so many people just throw in the towel instead of doing what it takes to make their marriages work? No wonder there is a lot of cynicism regarding marriage these days.

I will say four words to you , Dark side or bright side?

Dark Side : is the place you going to end up staying if you have affair with your husband best friend , and that place full of depression and stress , and you going to commit suicide too and coupel of month or days later , and when you die , you will not going to have peace, you will end up burning in hell


Brigth Side: Stay with your husband and clear your mind up for the dirty thoughs, and think about to have little kids have hid eyes and your face too and you going to live happly ever after

You do nothing! So you love the guy. So what? Stay within the boundaries of good behavior and respect your husband, your vows, and yourself, and keep this guy in a fantasy world where he belongs. Just don't let him cross the lines of fantasy and reality.

Its not who you love, because its natural for humans to love, but what you do about it is what will define you as a lying, cheating whore, or a dedicated wife, and mother, and good human being.
