As has been noted, you've been married for a very short time, no kids. The chances it was "just an emotional affair" are pretty low. Think about probability vs. possibility. It's possible it was only an emotional affair. It's much more probable it was a full-on physical affair. For a man, this is pretty much a death knell (ask me how I know) for deep and abiding affection for your wife. You may even find yourself feeling dead "down there" for her for a long time, because your body has simply decided to reject her -- and trust me your body will decide things firmly with conviction without consulting the squirrel running around in your brain.
It happens.
In any case, she's been giving you dead bedroom or starfish sex since the honeymoon, so functionally it doesn't seem to matter all that much.
So two things:
1. Only an attorney can best advise you, but in many states a short marriage does not entitle a spouse to "half." In some states you can still sue for alienation of affection in cases of infidelity. So seeing an attorney is a must.
2. Seeing an attorney is also a must because many times here on SI, a majority of folks look at a short marriage and no kids, and if infidelity is involved they recommend the faithful spouse get out as quickly as possible.
Because if your wife couldn't even be faithful in the honeymoon/newlywed stage, how do you think that will shake out long term? Also, because this has happened so early, you're left with a permanent stain going forward that will never wash out. Many reconciliation attempts are based on a long and shared history, kids, entangled finances and more. These are legitimate pragmatic reasons.
There are very few pragmatic reasons that I can see for you to remain shackled to the source of your excruciating pain. Her very physical presence is going to be a trigger for you from now on. Subjecting yourself to the mental and physical (adrenaline, cortisol, elevated BP and heart stress) damage from this is a very bad prospect.
and just get back to where we were in our first year together.
Gently, this is never going to happen. I don't mean to be overly blunt but you're never going to get back there. The marriage as you knew it is over. You can decide to try for a new and different marriage with her, but that is really far from ideal in your particular situation. After all, this is the same woman who by your own account already betrayed you before her affair by denying you intimacy right after your honeymoon.
Look at her with clear eyes. She's showing you who she is. She's not who you thought she was, and I'm sorry about that. We all are.
It would also only be common sense to also question exactly why she ended up divorced with two young children from her previous husband. I'm sure you've thought about that. I think you should, and I think you should dig a little deeper than whatever story she's told you. The withholding of sex so soon after your honeymoon seems like a classic red flag to me. It smacks of a woman who manipulated you into marriage for financial stability, and little else.
Science shows that once the "brain barrier" for infidelity is broken, it makes it easier and easier to repeat the actions with little or no guilt.
I suggest you run a version of Pascal's wager "stay vs. go" calculation on this as a thinking exercise. My guess is your wife will come up short on that.
Just my two cents.
ETA: The Pascal's wager in this case would go something like...
Weigh the gain and the loss in wagering that you should leave the marriage. What do you stand to lose by leaving? Not much, since you've already lost it.
What do you stand to gain by leaving? At least a fair to middling chance at a better life than what you have now.
What do you stand to gain by staying? Not much, since you'll be gaining the woman you're looking at now with clear eyes.
What do you stand to lose by staying? Your health, your sanity, your own feeling of inner integrity, your daily happiness.
So okay then. If you gain by leaving, you gain much -- your sanity, your health, possibly a new and different wife (or at least a girlfriend who respects you more); if you lose, you lose relatively little (because you've already lost a faithful wife in such a short marriage).
In Pascal's formulation, wager that it's better to cut your losses. There is a happy life to gain, a larger chance of gain against a smaller number of chances of loss (and a higher number of chances to lose if you stay with an unfaithful woman).
