I sense you are locked in the same loop that hung my life up! Please value your inner happiness and really ask yourself if it was all that great to begin with. I say this because when WH finally broke down and proposed marriage to me after years of casual dating, I had no great joy about it, more like "well we have been dating for 4 years (platonically I should add) and I'm 'of an age' (I was 42 and tired of 'user' men and he was not like that because I never allowe him to be like that!) So after talking it over with some friends and family - who all thought he was a good guy - I said "yes."
Had I but known what awaited me!
My father even said to me once, after we'd been going out for 2 years or so when he came over to my house and my BF was there that watching us, he could tell I wasn't in love with him. I replied "I know, Dad, but he just won't go away!"
What that should have told me is my abandonment wounds were still raw from a couple prior disastrous romantic entanglements that had eaten up 13 years of the prime of my life after I'd left my first H (who also had cheated, as I found out once I was leaving him, 5 years after the fact and being forced to walk away from a big house I'd designed and built for us that he let go to foreclosure! I'd only agreed to marry him because he begged me, and my mother was scandalized by us living together.)
So I've spent a total of 29 + 13 years married to partners for whom I only feltwhat I'd call "lukewarm" affection, but here's the key: that seemed enough at the time, Ouchy! Then on top of all those unhappy married years I wasted another decade getting my hopes up for years on end then getting them dashed, and then eventually Mr. Steady Eddie came along. Hence my comment to my father.
But once I discovered my WH's brain had no problem splitting sex from his vows, all my calculus on choosing him was trashed. I was on the floor sobbing because it felt like my whole life had been one mistake after another. And we'd had such a pretty, grand-scale wedding, something I'd skipped when I was 19. It all crashed and burned. Except I had re-mortgaged MY little house, the first one I ever was able to afford as a single woman, in order to get funds to buy a bigger place with room for his hobby (mechanical work). The divorce attorney I immediataly saw after D-Day 1 warned I was in a terrible situation, because we were hundreds of thousands in debt by then and he is not a citizen of this country so he told me he could be a flight risk if we pursued a settlement that would make me whole. And then he asked me "How would you pay for all this if we got it for you?" I just had left my career 2 years prior to follow him around the globe as he travelled a lot. So I did what the attorney suggested, mainly because, having lost my first home I built, I wasn't about to lose a second one to some man!
So please don't do as I did, it was such a series of compensations for other deficiencies that kept me "hooked" and not wanting to start over.
The reason I returned to college at age 55 was to study counseling psychology because of the bad therapist we'd had...I felt she defrauded me of my rightful process in sorting out what was wrong with this relationship I had chosen to end, but she wanted to "work with us both." and he came along...(By the way she was an Imago therapist and it is not helpful with ND partners, as they cannot MIRROR and they don't "get" the other's emotions that way.) Then during one-year of intensive weekly MC sessions, the second counselor suggested I had a gift for that kind of MH work and I wanted a career change anyway. But my schooling was mostly to assuage my own mid-life devastation.
So save yourself the bad investment of your time and youth, which you still have! The glass may look half full to you right now because it is early days but this issue of not allowing you the agency to decide about your own future is pathological, full stop. I know that's harsh. But the manipulations of a self-centered individual blinds them to their own destructiveness, as they want their cake and eat it too, as you already said.
