Infidelity Support Group
Any relationship in which one partner engages willfully in sexual relations with another outside of the partnership is considered to have experienced infidelity. This breach of trust is often traumatizing for the faithful partner as well as the relationship, and support is often needed to heal emotionally and to decide whether or not the relationship should continue after...

I believe it takes just as much work to reconcile as it does to split and heal oneself. To reconcile, you still have to work on yourself...if you don't those feelings of rejection, pain and hurt will never go away. Takes 2 to really make that work.
My stbx is a narcissist and what she did to me and the number of men she was involved in, made my choice easier. I was not going to put myself through all that work to save this marriage because I knew I'd be the only one to be willing to work at it. She checked out of the marriage long ago.
My decision was still hard, but I'm looking after myself and as time goes by I realize how toxic this relationship really was. I'm moving on...that was my choice
What ever you decide...you will have to work. There's no easy way. I wish you the best. Be well and be strong.
That's where it differs for everyone. Some CS (cheating spouses) really DO the work, make a 180 degree change, commit to all that it takes, etc. That said, it still is very hard even when they do that. We were "reconciling" for about 3 months before it ended for good. He tried to get me back several times after that, and has made statements that lead me to believe that to this day, if I gave in, he would want to come back. But it will never work for us. The damage done was too great, he ultimately could not fully own what he did, he did not change but only got sneakier. His lies were too many, and trust cannot be built.
So, I hope for you that if you want to repair, you can. I know not all people are like my ex. However, and this may seem harsh, but trust me, ALL cheaters have a few things in common.
They LIE. You have to lie to yourself, your spouse, and to others in order to have an affair. Therefore, again, it may seem "impossible" to you now, but trust me that she is a liar. Do not take anything for her word at this point. If you do, you'll only get burned. Trust has to be rebuilt, she broke it, and it won't be rebuilt overnight. She needs to give you access to ALL accounts, passwords, emails, cell phones, where she is at all times and with who, etc. If you fail to get these and take her at her word, that leaves the door wide open for her to continue or resume an affair. If she refuses to give these to you, or acts wounded that you want all of this, that is a huge red flag. No secrets, no privacy, for a very long time, if not forever. It IS necessary.
Not necessarily "once a cheater, always a cheater," but YES, unless they are willing to do the hard work and intensive therapy to get to the root, within themselves, of how they were able to justify such a selfish and devastating act. If she blames you or justifies it at all, that is a huge red flag.
Were you a perfect husband? I don't know you but I know 100% no you werent. Because there is no such thing. Literally every couple has problems. Literally all humans are self serving in some way or another. We all have flaws. But guess what??? That's no reason for an affair!!! If she says it is, or even alludes to that, again, huge red flag that she feels entitled to cheat instead of dealing w couples problems in a healthy way. She could have talked to you about her concerns with you, asked you to go to therapy, or even ended things with you. But instead, she decided to cheat on you. You do NOT deserve it. No one does.
Staying "for the kids" is what many people jump to, but it never works. Will your life turn upside down in a split, for sure. But it already has, and there is no going back, regardless of your choice. If she does the work, something new can be built. But if not, you will be keeping your kids in a dysfunctional home. You will be teaching them that 1) it's ok for married people to cheat 2) they have to accept it if someone cheats on them. Yeah, they are little now but they don't stay little, and eventually they will pick up on things, especially if your wife doesn't change her ways. Kids are super intuitive, beyond what we give them credit for.
It is hard to see it now, an affair is like a death. You will go through the stages of grief, like with a death. Denial and bargaining are often right at the beginning. Anger, depression, eventual acceptance will come too and you may go back and forth in stages. Don't make any permanent decisions to stay, accept, trust, allow, etc right now, because you are in denial and bargaining, which is normal.
Sorry, I don't mean to be doom and gloom, but a dose of realism is helpful. Successful repair is very hard. Only you can decide what to do, and in reality it may be too soon to know. It is not an easy road regardless. Keep up with the therapy. Coming here helps too, although this board can be hit and miss, sometimes there are more people over on Divorce/Breakups and Healthy Relationships, if you aren't getting replies here. I truly hope good things for you. One website I do recommend is ChumpLady.com. Some of her wording upsets people who still have their cheater on a pedestal. However, she tells it like it is. Worth reading.

There is another group here, 'Cheaters Anonymous' where some betrayed spouses like yourself look to find understanding and insight into the thought patterns of those who have been unfaithful. Some believe the group normalizes the behavior in a negative way (believe it or not, we are humans too, many with a very loving and compassionate outlook in life). It may help in your healing process to explore where your wife may have been coming from. I believe empathy is always an asset to any difficult issue. Forgiveness is not an easy path, but it's possible.
I agree with Happymama2j, that being realistic about this, is paramount, and it can come back to bite you in the ass. There are hard and fast guidelines that must be adhered to in order to culminate an environment for a successful reconciliation.
The part where you say you fell out of love and became disconnected for two years, isn't something to just sweep under the rug. I'm thinking your love feelings have come back as a reflex of the infidelity, and your attempt to secure what you know. There's a reason why you fell out, and without analyzing it and getting to the bottom of it, it will only repeat itself.
I wish you well
