Teal'c is a terrible husband.

Rewatching SG1. In the episode Crossroads (4.4) Teal'c's ex love interest shows up, he is shown to still have deep feelings for her, and if memory serves, even spends the night with her. At this time his wife Dray'ac is still alive and living in exile. Not only does he not acknowledge Dray'ac in the episode but after Shan'auc death he spends the next 1.5 season avenging her death.
