That's a good attitude Corbean. Buy expect hills and valleys as this all plays out. One minute you will really good, and then a rogue wave will come crashing over you, and then you will bad again. Expect these feelings to happen because they are normal.
I remember when my ExW left and then began an affair I went through the same thing.
I eventually recovered and moved on and guess what... suddenly she came knocking on my door. By that time I was already dating someone and my ExW lost her mind. She even told me she had thoughts of suicide because of what she had done. By then I was already moving on and happy with my new girlfriend.
Like the title of thread says... Fasten your seatbelts.
