If Jinger is fine with delaying pregnancies, good for her and good for the Holy Goalie. I'm not his biggest fan, but he's made good decisions so far, IMHO: Told the families that they would not be visiting for six months so he and his wife could get on a good footing as a couple, bought a house, and (maybe) are looking for a pet so they can see how it goes with another being that depends on them for care before the babies arrive. Hopefully they are saving. I also think he is positioning himself to get on staff at a megachurch in a larger city; he'll be shaking the dust of Laredo off his shoes if and when he gets a job in Houston or Dallas. I hope Jinger is able to find something that interests her (photography, perhaps?) and take classes to enhance her skills as well.
Again, I think HG is controlling but in some respects, he's smart. Their marriage will survive because they actually are getting to know each other as people and they do not have KJB and J-Chelle breathing down their necks and "dropping in" to offer "godly wisdom". I am guessing that KJB is already regretting allowing the marriage, especially if he discovers birth control is being used.
