Hi Charlie,
I am really sorry you are going through this!
I too have an AW and two children. I too am new to this forum. I too have had my trust discarded by the woman I love(d.) I can really relate...
What has been helping me:
1) Reading and posting on this forum!
2) Taking care of myself. It has a real trickle down effect on my two boys; if I am content so are they!
3) Picked a few little crappy behaviors (that I own) and eliminated them from my life. Example; now I walk right by her usual booze-hiding spots... never poke my nose in... (might sound easy... this was tough for me) I have gained back control, I am less frustrated, I have more time (go figure) and see #2 above.
