My uncle started studying because he wanted to date a JW girl. He got baptized, they got married, and he went to prison for neutrality during the early 1960s. They are still married - their 50th anniversary was in 2010. He's an elder, very active on the RBC. I don't really think my aunt is happy, she's in poor health and they don't have much income. SHe's not able to pioneer anymore due to her health issues, and all their children are dead. I don't think either of them really has any doubts, but neither really seem happy.
The other couple I know, similar initial set up. Worldly guy interested in a sister, she won't date him unless he gets baptized. Difference is this sister is older - 30 rather than 15, and has two kids from her ex-husband. So he studied, got baptized, and they got married. He was made an MS fairly quickly, and then an elder. WHile serving as an elder, he got busted having an emotional affair with a coworker. He swears he never commited adultery, and his wife doesn't want a divorce. She's a stay at home mom homeschooling two preteens, and she really doesn't want to do the whole single mom thing again. They are still together, but he quit coming to meetings and he's grown a beard. I've heard that he told the kids he "doesn't believe it's the truth anymore", but I guess he backpedaled so as to avoid a DFing. As best I can tell, they are both miserable.
