Welcome to the club you never wanted to join. No one wants to need this place, but it is really a great place to be when you need it. You’ll get lots of support and lots of advice here. Take what helps you immediately. Think about the replies that make you feel uncomfortable before rejecting them outright. And leave what you decide doesn’t help in the moment—you can always come back to it if something changes or move on from it completely if it misses the mark. Everyone here has been through infidelity, and it has devastated every one of us in different but similar ways. Everyone here wants to help and support you.
So first, huge hugs of support and strength to you. My first advice is: keep this place for yourself, your safe place. Don’t share it with your WH right away. You need someplace that is just for you to share, vent and get support.
This is the worst kind of life-altering shock. I’m so sorry. We’ve all been there at that moment when suddenly the whole world as you know it is changed, your spouse is a complete stranger dressed in the skin of your best friend, and the life that you loved and thought you were living is just. . .gone in a second. It can really leave you disoriented and grieving,
So first, take care of yourself. Make sure to hydrate and to eat when you can. Take time to do whatever can help you feel calm and relaxed even for a few minutes.
And now, gently, I’ll say that almost no one gets the full story this early on. Have you considered how very unlikely it is that he was with someone just the one time and that happened to be the time she got pregnant? Not impossible, but experience on this site will lead most of us to say it’s not likely. Many WSs only tell the barest minimum of what they need to disclose—often they only admit to what is already found out and verified by other means. It’s very likely that there will be more shocks and more discoveries to come as things proceed. It is even possible that she wasn’t the only affair he’s had.
I say this not to upset you but to warn you that the one common denominator of cheaters is that they lie. They had to lie daily, every day, to you and quite possibly to themselves in order to start and have an affair, and then they had to lie to you (at the very least by omission) every single day since by keeping such critical information about your life and marriage from you.
And the financial aspect is indeed another betrayal. He allowed himself to risk your health (from unprotected and undisclosed sex with someone else and your mental and emotional health from discovering his betrayal), your financial stability, your marriage, your life together, your future. Infidelity is a traumatizing betrayal of the highest magnitude.
Has he done a DNA test yet? Have you both been tested for STDs? Has he offered to take a polygraph to assure you that you have full disclosure of the extent of his betrayal and any other possible affairs? What is he doing to own this and help you heal—whatever you need for that?
Many more will be along to help. I hope you are finding moments of peace. Keep posting and keep reading. For most of us, this can be an extremely lonely and isolated road. Sharing and reading here can be a great source of help in navigating a road that none of us expected to have to walk.
