Ok now that we have beat your about the head and shoulders with the fact that we all think he is full of shit, I want to say welcome, and offer a few gems of information for you.
Welcome to the best club NO ONE ever planned or wanted to join. You will find many wonderful people here. Some of us far out from the infidelity, and healed, some in the middle of the journey, and others just like you, just realizing that your world has been turned upside down.
There is a library up to your left side of your screen it has tons of great information in it. Start reading. There are other posts in the Just found out forum (JFO) with bullseyes, I will bump them. They too have great information.
Right now you are probably feeling confused, weak, embarrassed, and scared. All normal. Let's put some of these feelings where they go. Embarassed - You Have ZERO to be embarrassed about. This is all on your Spouse. He did this, and if anything you should trade the embarrassment in for anger at his selfishness and stupidity.
Confused- hell yah you're confused, the one person who you could count on to be honest, and true, has now proven himself to be a liar, and untrustworthy, you are also confused because his story makes no sense. That is because he is still lying. As you read you will discover that he doesn't get to be in charge of how this plays out. YOU DO!!!! but only if you take charge.
Scared- Fear of the unknown is the scariest feeling in life, as far as I am concerned. The what if's can be almost paralyzing. I would urge you to arm yourself with knowledge to take away the what if's, and allow yourself to be empowered.
Weak - This was a bad one for me, I kept saying if only I had done x, y, and z he wouldn't have done this. Frankly that is self defeating bullshit. He is doing this because he is a broken man. There is something in him that desires the attention, ego stroking, fantasy. He has to figure out what that is, and why, and fix it.
So you have STD testing, please tell me that included HIV, and Hepatitis screenings too. If not then call your OB and have them ordered immediately. Also if the stress of all this is too much, and you are having trouble with sleep, and eating, then let your Dr know. This is quite possibly the most difficult thing you will go through in life, and many of us have found medications can help. Everything from Antidepressants, to antianxiety meds to even treating our ADHD when we haven't had to our whole adult lives. There is no shame in it, and you need to be sleeping so you can keep your emotions in check, and your brain working well. Same with eating.
See a lawyer, no matter how this can or will turn out, you need to know your rights, and his legal obligations. He is running around having unprotected sex, you need to know how to protect yourself financially, and protect your kids financially.
It's up to you, but Do NOT leave your home if you want some time away, send him packing. This can be a real eye opener for the cheater, it makes them realize that you are not going to tolerate being disrespected, and also makes it very real what they stand to loose, home, wife, kids. Until this point it's just a possibility, and had he not gotten a disease, wasn't even on his radar of getting caught.
Keep reading, keep posting, and know that we share our words, advice, and recommendations based on caring, and wanting to prevent you from making some of the same stupid mistakes we did.
((((and strength))))
