At the end of The Endless Knot (the third installment in the Song of Albion Trilogy), Llew suffers through fire and hell to be reunited with his wife, Goewyn, just to get stabbed in the chest by his best-friend-turned-enemy. The author described it both more poetically and in much more painful detail than that, obviously, but I'm trying. Afterwards, Goewyn and Tegid (Llew's trusted advisor) have a painful conversation in which he insists that she must let Llew go, lest her love sicken in her and slowly kill both her and the child she carries, but she at first insists that she will keep him by her side forever. However, with enough coaxing, she finally relents, but not without many tears.
