Wife took everything i loved or owned and gave to an undeserving home wrecker?

I am a hard working 35 yr old loyal honest good looking man and my wife that i deeply cherrished recently left me, took everything that i treasured in life. her the kids the house the car furniture tools even the toilet paper spindle. she wont talk to me she wont communicate at all. if i try she took a restraining order out one me. i felt powerless. i still feel that way i have been best friends with her since we met when i was 5 yrs old. no arguements lead up to the seperation. i came home and she was gone with everything. what really hurts is the man she gave it to is a multi offender homewrecker. his proffession was meth dealer not very succesful though he never has any money he has three previous wrecked marriages on his belt with children involved in all of them. my question is how do i stop him from doing this again? how do i stop the deep hurt of betrayal inside of me? i know the typical answers move on with life pay him half my check for taking everything from me.
