I never know the right thing to to....

This has been an interesting week to say the least. I have not really been in the Christmas spirit but I learned this week the scumbag that my ex ran off with, my former best friend had been steeling more than just my girlfriend. I got a call from his wife asking if I was interested in getting back some stuff he had taken over the years from my company while employed here. I asked what she was talking about and she informaed me that he accumulated alot of my tools and material and if I wanted it... I was welcome to it. Not knowing the extent of the items, I asked the local Sheriff's office to go with me because I didn;t want to get blamed for anything and discovered, table saws, power miter boxes, hydraulic punch kits, ladders, large circulating fans for construction sites and countless boxes of raw electrical materials. The Sheriff and my brother, a retired police officer, both said while its incredible, forget about further aggrevating myself and forget having him arrested. Just get my stuff back and get the hell out of there. I am not sure what to do but I will be getting the stuff back Monday or Tuesday. I also found out that he was scrapping thousands of dollars of copper wire, none of which was his.... The problem there is that the scrap yards all pay in cash!
On a second note, I also am struggling with the idea of getting my ex's son a Christmas gift or not. If I did, I would simply give it to his grandmother to drop off from Santa and keep my name out of it. I love this young man as if he was my own and to not do something for him this Christmas would kill me inside. I do NOT want to see or hear from his mom (the ex) but he didn't do anything to me and I miss him so.
I am just venting a bit and taking one day at a time.... I continue to heal but really have to fight off thoughts of them all the time.
