Kjs, you sound so much like me a few years ago, it's almost spooky!
Please, PLEASE, PLEASE don't take what I'm going to say the wrong way, OK? I know how much pain you're in right now and how your whole world has been turned upside down on you lately. But I really don't understand your answer to the therapist when he asked you what ONE thing would you most would like your H to do ... and you stated that you wanted him to be more involved with your sons school work? What about how he completely discounts your feelings, how he belittles and demeans you, how he continues to lie and denies his porn addiction/habit even in the face of written proof, how he lets you work yourself half to death and doesn't seem to care, how he hasn't even touched you in FOURTEEN YEARS!?!? And you said, "School work"? Maybe that's the reason the therapist asked you that question several times.
Your visit to the therapist sounds, almost word for word, like the ones my ex and I used to go to! He said he wanted 'less yelling' too! Less fighting. What he meant was that he wanted to deny the HUGE problems we never even discussed with the therapist and he wanted to continue on just as he had been, only with less interference from me and less 'fighting and yelling'! And I too tended to gloss over the HUGE issues that were really the problem ... like his alcoholism, his abusiveness, his violent rages, his infidelity ... because I still tended to blame myself and still kept thinking that it was MY fault somehow that he treated me that way. Truth was, I was embarassed and ashamed that he obviously thought so little of me, and I didn't admit it even to the therapist. I didn't share that with anybody! So we settled for "keeping the peace" and worked on that - fair fighting and all that - and of course, that didn't last for very long. It was simply putting a bandaid on the major problems, for the sake of "getting along" and "less yelling". PLEASE, don't you 'settle' too, just for the sake of keeping the peace!
And you too have some HUGE issues to deal with here and he seems to be in complete denial. You need to seriously ask yourself what you're getting out of this 'marriage' and why you are so desperately hanging on to what's left of it. I told myself that I was sacrificing myself, my own interests and well being, for my children, and I was willing to do that. But in truth, making that break was the best thing I ever did for them! When he was finally gone from the house, when all the conflict and all the fighting and his disruptive influence were finally gone and all was peaceful and quiet, the kids seemed so much more relaxed and happy and their whole world changed for the better. I only regretted that it had not happened sooner. It appears that you are getting absolutely nothing from this 'relationship' - nothing but heartache and conflict and tears, your confidence undermined and your sense of self-worth ruined. The unknown is a very frightening thing and sometimes it's so frightening that we are willing to put up with things as they are, rather than to make drastic changes. I won't presume to tell you that it's easy being on your own or that it's not frightening at first, but these things have a way of working themselves out and you will soon be AMAZED and how empowered you will end up feeling as your confidence in yourself returns! You deserve so much more than what you have been putting up with! PLEASE don't allow yourself to merely settle for 'keeping the peace'! You so deserve to be happy! And you just might find out that when all this is resolved, many of your sons issues will improve too!
