Hello.
I cannot speak from personal experience but can relate some of others experiences who have left messages here and make a general comment.
For any good relationship, I would say that what is important is either or both mental equality and/or mutual respect. That is to say, where there is not mental equality between the partners, at least their can be mutual respect for each others special abilities.
I come from a different culture where it is entirely possible to have relationships, more than one relationship, without marriage. By that I mean "serial monogamy" ... not multiple relationships at the same time (infidelity). People live with each other for as long as they want and then split and move on some finding other partners, others not. It is left to the individual's choice. I understand that most of India does not follow this pattern.
It would seem to me that the hardest part for BKs re-adjusting to ordinary life is that BKs are mostly used to a highly self-disciplined and reflective lifestyle. They are encouraged to become "selfless" - which I think is a good thing - ,but unfortunately, that personal selflessness is exploited for self-interest of the organization of the BKWSU.
Not everyone has these qualities of selflessness, self-discipline and reflection ... especially moral self-discipline and moral reflection ... and I think the hardest part of engaging into a relationship is living with someone that does not. In my opinion, most of life for most people is a bit of a fight for one's own self-interest and being a BK, and seeking to avoid conflict, might not actually prepare one for that. It may take time to relearn, it might be difficult to adapt and be accepted into an environment where fighting for one's own self-interest is normal.
(Of course, even some BKs do not have these qualities but they are a minority I feel and so I exclude them from these thoughts).
So, my primary advice (peer/mutual support), would be to look for someone with such qualities of self-reflection and self-questioning with which one can continue to grow spiritually but other qualities are important too. Someone who is more down to earth might be a good balance.
The other most important issues would be to discuss very openly what you have been through and why. This might be less of a problem in India where spiritual seeking is more common. Don't hide it, but avoid falling back into the habit of "serving" non-BKs!
Real life is interesting. There is plenty to do. There is plenty of good to do. You have to re-consider your own personal security. "Serving others" if that still interests you, is not limited to preaching Brahma Kumarism ... you can still give to and help others in many ways.
In short, leaving the BKWSU for me, is about becoming one's self again, picking up one's own spiritual or life path, learning one's own lessons, in religious terms, "becoming one's own master". My feeling is that we were conned by being sucked into the BKWSU and taken off our own path to walk someone else's, to serve their ambitions and their self-interests not our own.
Life is not always easy. Success and failure are part of life and often beyond our control. But it is better to be one's self and learn one's own lessons rather than someone else's.
In many ways, you - as a male - were made to be a wife. A wife to the Seniors, to BapDada, to the BKWSU ... by that, I mean more submissive, passive and subservient. It should have made you a better person and made you more capable to be a better, more sympathetic husband too! But you may have to re-learn some of your strengths.
In balance, would I do it? Yes, is the answer. Move on. Leave that life. It really is only becoming worse and more exploitative.
Do not worry about God or gods too much. Be a good person and if they need you, they will come and ask themselves ... they do not need some old women in white to ask for them and take a commission in between.
