Everything you said, about what you were doing while he was cheating, the trip to Vegas, taking care of your mom, etc., all feel like such betrayals and they are, but all of us have had to deal with those betrayals and many of us are still together.
First you need to know you are not alone. Looke at your member number. That is how many people that are on this site alone. This happens in good marriages, solid marriages, marriages that you never thought that it would.
It does though and we are left to deal with it.
The pain you are feeling now will get better. It will take time, but it will get better. Keep posting, find someone you can talk to, limit the number of people you tell, and get ready for the roller-coaster ride of your life. Hugs.
My only advice is to let the dust settle before you start making big, permanent decisions. This whirlwind state is not a good place to make important decisions from.
I'm so sorry you're here.
I know the marriage is 50-50 problems but the affair is all his. Since I confronted, he has shown very little remorse. And In fact, tonight emailed that he "has an addiction" and shouldn't I understand that? No... I don't. This is all his doing.
Our confrontation was Jan 4th . In five days he has responded to at least 5 woman. This is sick, right?
New Mantra: You were my best friend. Now you're someone I used to know.
You have seen what he is capable of. It is sociopathic and he isn't even trying to stop what he's doing. He is carrying on and thinks you will put up with it.
You know what you have to do.
I am so sorry you are with us.
hugs to you
