LMAO. He wanted everything in that marriage. He wanted Winterfell, as he thought to himself, and he wanted her in the physical sense and he also wanted her to love him. He didn't warn her about the marriage in advance (he knew at least a week before) and let her be shocked by Cersei with her "you can run but you will be dragged to the altar by the same men that beat you" approach on their wedding day. He did offer her to stop their marriage, but she was still getting married in a few minutes to a Lannister and her only other choice was Lancel, the guy who participated in her abuse. What a great choice that was, huh? "Someone she found more appealing" would be Loras or you know, Willas. The guy that Lannisters, including Tyrion, wanted to stop her from marrying, which was the reason they married her to one of her own.
Let me guess, you are also forgetting that he made her strip for him, groped her breasts and forced her to look at him naked, while knowing that she didn't want any of it, before oh-so-heroically deciding he didn't want to rape her?
But I guess he was kind of nice. For a Lannister participating in a power grab. Which may be the important part when we are talking about the forced marriage of a 13 year-old girl in order to steal her inheritance which she is only entitled to after her brother gets murdered.

Yeah, we disagree. Shae is dead after being slowly and painfully murdered, and Bran is thankfully alive, so I count him more lucky. What Jaime did to him is still horrendous, as well as his hunt for Arya and threat towards Edmure.
