Just sending you my support. You are in the most difficult time now. I know that the stress is unbearable.
Regarding 'emotional fusion'...I had to read it twice because that actually sounded like a GOOD thing to have in a relationship...but hey, look at how screwed up I am so don't listen to me!
Of course you are taking your wife's rejection "personally"! Good heavens woman, who wouldn't! But your wife is screwed up right now and I still feel that you are taking 100% of the blame in your sitch, when in reality, its 50/50. Your wife is an adulterer - that is not your fault. It will never be your fault.
I know you are just trying to *fix* things, but don't let that become a way to beat yourself up for your core personality traits. Your W ultimately needs to love you for YOU: the caring, responsible friend and loving mother that you are to your son.
I wish I had more to offer you for support or advice, but as you can see, I haven't been very good at 'busting' my own sitch, so I'll just say, keep hanging in there my friend. There has to be light at the end of this tunnel.
