OP, you have gotten a lot of really good advice here. It can be very scary going through this as a SAHM. Can I add just a couple of points here?
1) Many women stay with their husbands after infidelity. This is your decision alone to make. Do not allow the posters who are trash-talking your husband based on a short paragraph to influence your decision. There are reasons men cheat. And a good therapist can help him sort through these issues. A therapist can also help you sort through your feelings as well.
2) You will get through this, whether you stay or leave. Divorce is devastating, no doubt. But both adults and children survive it everyday. Do not feel this is the end of the world for you and your children.
3) My mother always said, "Expect the best but prepare for the worst." I wholeheartedly agree with the previous posters who advise you to secure your financial assets now. You do not have to make a decision of forgiveness/non-forgiveness just yet. But remember that you have worked hard to support your husband in his career, and you deserve your share. So do your children.
4) Do not underestimate the control another woman can have over your husband's mind. There is always the chance that he could emerge as someone "you thought you knew."
5) Pray to whatever god(s) you worship and ask for strength. That strength will not only tell you what the truth is regarding these hotel charges, but it will help you make the right decision on whether to stay or leave.
This is helpful. I suppose the unclear part has to do with Spanish as the primary language spoken in home (according to the requirements). It doesn't acknowledge folks who are a bit more gray; for example, a household that mixes both Spanish and English or a household with one Spanish-dominant parent and one English-dominant.
Is it possible to get into the Oyster school district for $800K or less? There's nothing on the market right now, but I'm just wondering if it's even possible.
