peg10,
I just came across this thread today or I would have posted to it before.
I am an Army officer with more than 30 years service and I have seen this before.
First and foremost, your WH is treading on dangerous ground with his career. What he doesn't realize is that even if you do not expose (and you absolutely should) if the wrong person finds out he will suffer the consequences.
You have indicated that the OW is a local woman so I am assuming that you mean a local national rather than a US citizen who works at the Embassy.
You may not realize this, but his involvement with her will probably cause him to lose his security clearance. I have seen this happen to a full Colonel who was married and had an affair with a local woman.
*He is due for promotion soon and this can hurt his chances
Perhaps, but it won't be you telling that causes this, it will be his having an affair. Besides what if he does end up divorcing you, OW could reap the benefits of his promotion.
*He may get angry enough and stop finacially supporting us
No way the military will allow him to stop supporting his family. If he fails to do so, they can take UCMJ action against him and/or force him to have an allotment taken directly out of his pay and sent to you.
*His family will no longer be supportive and even my own brother is against it (retired military)
Too bad, they are not walking in your shoes. You are fighting for your marriage, not their approval.
*His commander may do nothing at all
Maybe, but even he/she has a superior that you can bump this up to. I am surmising that if he works in the Embassy and is in uniform that his supervisor right now is the Defense Attache who is also military and that they are both assigned to Defense Intelligence Agengy. If you want contact information at DIA, email me direct, I used to work for a former Director of DIA.
*I worry that he will distance himself ever more from the kids now and in the future because he is SO angry.
Do you think him possibly divorcing you and marrying OW will bring him closer to the kids?
In a word, you need to use the powerful tool you have in exposing to his superior.
Best,
Who
