To start with i want to say, welcome to 4WT girl, and you have come to the right place...

Now to be very honest, this "friend" is not a true friend if she can do that to you! I would cut ALL ties with this lady, she doesnt deserve to be called "your friend" but that's just my opinion.
Not only did your hubby cheat on you, so did she and that's got to hurt.
In time to come, you will be able to forgive, but it will always be in the back of your mind.

As mentioned above, going to a counselor will give you strength as he/she will unfold things and put them in line for you to get a clear view of things.

Good luck and stay strong, we are here for you!
