Hi Jeep. Write the letter then burn it. You not giving yourself time to let your feelings settle Firstly you do not want this version of your W back. , you deserve much better.

You both made mistakes but only one of you acted in a horrible manner and disrespected the other.

Only you know if you can truly get past what W has done but you are not in a place to decide that yet.

Give yourself time to accept what's happenedc and let your feelings settle

Please do not send the letter , it will achieve nothing but show W you will accept anything she does

Just my humble opinion.

Take care. RD
