Comments about ‘Gay LDS men detail challenges’

I've been married to my return missionary for 17 years, we have 3 children together. He was sexually abused by 2 men in his adolescent years, was raised by a disconnected father, and over-bearing mother. As I believe, there are a very few handful of people that are 'born' this way, I think the majority fall into his/this catagory of a history of abuse/neglect. Though he has not had a physical sexual relationship with another man, he has been caught, on more then one occasion, of entering gay men website/chats. I believe he has potential to change and I sincerly would like to keep my kids in an 'intact' family, but not sure how much I want to continue to sacrafice? He is awonderful and active father, and provider. I do have a career and supportive family but, it is a VERY lonely situation to be in. Suggestions/advice...please!
