I took a break, but I'm ready to do the hard work now (to feel good about me!)and I need your help!

Here is my story:

Married 30 years ("non anniversary" yesterday)
One D16
H had on/off again affair(EA??) for 3 plus years (we lived together the whole time). He was always honest about it.
July 2006 he asked me for a D
July/Aug 2006 worked with divorce mediator. H moved out.
Sept 2006 H said he changed his mind
Mid April 2007 changed his mind again: H said he needed "space" (moved to our new boat---I thought it was the new hobby that would bring the joy back to our marriage)
Mid May H started talking divorce again. (He hasn't filed, but gave me a proposed financial settlement. He is waiting for me to respond). I also started a thread over in "surviving" to get some help re. settlement issues. I interviewed a lawyer, but haven't hired her yet. Need to do this soon!

SO, here is what I need to accept:

1. I gave a 100% effort to save our marriage; H gave nothing.

2. I am NOT a crazy, jealous wife. My concerns re. his female friend that I wrote about between Sept and April were valid (My SIL verified this and I found a letter he wrote to this person). He is already looking for dates online (he forgot to sign off one night and I admit I snooped). Throughout our marriage there have been questionable "friends".....I was just too stupid to see it/confront it. He made me believe that jealousy was all in my head.

3. I will be ok.
