I have a brother in law (not LDS at the time) that dated my oldest sister from around age 16 to 20. My sister left him at age 20 because she knew that her life would be hell if she stayed with him, he was drinking alot using drugs and did not treat her very well. She loved him very much and it was a hard decision for her, they were high school sweet hearts. We come from a family that is LDS. At that time my sister was not active in the church for obvious reasons. Once she left him, she started going to church etc. Around a year later she was married (sealed) to a returned missionary. Needless to say another year later, give or take the marriage was annulled for reasons of he mislead her with what his life plans were. During this time my now brother in law started taking the LDS talks and quit drinking, smoking etc. Knowing that my sisters marriage was on the way out. My sister ended up marrying this guy and getting sealed to him 1-2 years later. We just found out that he has been lying to her about his drinking, gambling and general deception to my sister approximately a year into the marriage (not a surprise to myself). They have 3 children now and been married for around 16 years. On top of the mentioned issues, he has been sleeping with prostitutes for the last 3-5 years. My poor sister found out about this the hard way when she found she had an STD. When confronted he tried to blame her initially. Then the flood gates opened with what he really has been doing. She was devastated. They own a business that employs alot of women. He was also messing around with alot of these women also. To make it worse they live in a small town. Fast forward three months, now she has decided to try to work things out (how you do this with someone who is obviously very very selfish and I think incapable of treating her right). Now he has been told by professionals that he has a sex addiction as well as gambling, drinking etc. They are going to meetings etc. They have told there kids about the drinking & gambling but left out the climax of the situation (no pun intended).
