Dear Sobi
Like you, my wife had a feeling that I had a dark secret throughout our marriage and, on several occasions, asked me if I was gay, which I am not. Once I finally confessed my crossdressing to her, on the one hand she had a sense of relief that she was right about a secret being kept but on the other hand, she lost pretty well all trust in me and that persists to this day. After attempts on her part to come to terms with the situation, she gave me an ultimatum - stop or the marriage is over. I chose to stop but this has had two adverse consequences - firstly my urges to dress as (and sometimes fully transition to) a female have become a lot stronger (although they do come and go and, at the present time they have receded) and secondly I am once again being dishonest by not discussing how I feel with her (for fear of the consequences) and, more significantly, I am participating in this forum as what I consider to be a significant part of my psyche and personality.
From my point of view, nothing would give me greater pleasure than to be able to go to my wife and say 'look, I tried to cope with this but I can't. I have a female side who needs to come out from time to time - I don't know where this is leading but I need your help and support to get through this' and for her to reply 'it's OK, do what you have to do and I'm here when you need to talk about it'. Sadly, this is not and will never be reality leaving me with the choice to battle on as things are, resume my activities in secret or say what I feel and destroy our family. This may well be similar to what your husband is feeling at present.
Taking all of this into account, I know that I've been and continue to be a lousy husband to her. Yes, I think I'm considerate, try to look after her and do all of the things (and many more) that good husbands are supposed to do but it has been the intangible side of marriage that has been lacking - unrequited love, trust and all of those sort of things - and a major part of this has been my inner struggles with feelings that I don't want to have but can't shake off.
You say that you think 'something more is going on' but you haven't expanded on exactly what you think your husband is doing. Do you suspect him of something specific such as an affair, something about his past, is it a feeling of unease that he is still holding certain things back about the extent of his transgender feelings or is it just a case that you feel so let down by his deception that all trust in him has evaporated? Your husband may well be visiting TG related websites behind your back (he may even be reading these posts!), he may find transsexual women (or the idea that men can become beautiful women) attractive, he may be walking through women's clothing stores admiring the stock, he may be looking at women in the street and wishing he was them. These are all difficult things to discuss with wives and could give rise to his current general demeanour.
I have done a lot of soul searching as to the advice I can give you. In writing the foregoing, I have tried to give you an idea of how your husband may feel and what he may be doing but your post is about you. If you could be 100% sure that nothing else is going on, would you be prepared to accept that your husband wants to crossdress (and may wish to go further in the future)? If not, then I think your decision is made. If you are able to accept this, then how much are you prepared to be a part of it? For the reasons I put in my original post to you, I know this is incredibly difficult for you but if you do feel able to surprise him with an item of clothing or offer to help him with his makeup etc. it's possible that he will open up and enable you to have the more meaningful dialogues that you so desperately need. In suggesting this, though, I would caution you that seeing your husband fully dressed and made up may make you realise that these activities are incompatible with your marriage (this is what happened in my case) which, unfortunately, pretty well gets you back where you started.
The only plea I would make on your husband's behalf is please try not to punish him. He can't help his feelings and needs a degree of understanding even if this understanding is that, from your point of view, the marriage has run its course.
I hope this helps and you are able to find a solution that makes you happy but if I can be of any further help, please let me know.
