The Hook - Vital Plot Element or Unnecessary Complication?

Okay, you'll all be pleased to know that I'm done with the crows (until I hear from the eds I guess but NTAI!). My poor climber has been left to languish at a crucial moment so I should probably get back to him and give him his HEA. However, my sticking point is my plot. I have a fake engagement hook in the middle of it and though it stems from actions the characters themselves take, I'm wondering if it's a tad unbelievable. It's purpose is mainly to force the h&h together and maybe to deepen his conflict a bit but I'm still doubtful about it. Do they really need something to force them together? Can't they just be together because they're having a hot affair? I'm at 44k already and the black moment isn't coming for a wee while yet, so maybe my fake engagement is just an unnecessary complication...

The other thing I'm having doubts about is my timeline. Maybe it's just me, but does anyone else think that two weeks is an awfully short time to fall in love? Or is it just the nature of the genre and two weeks is fine and I'm being overly picky?
I don't know. Until I get over these stumbling blocks, I'm not sure I can finish the WIP. Might just wait until I hear back about whether the story is a goer or not.

Anyway, in the meantime, I have gone back to rewriting my Feel the Heat entry. It's so much better now I've got the conflict sorted! Since the editorial assistant asked me about it, I think I might submit that one next should the other one not succeed.

Ah conflict, how do I hate thee? Let me count the ways....
