Disrespect??? Namor saved Susan's marriage to Reed TWICE. He certainly seems to have more "respect" for her choice, than she has herself. I don't think it is all that 'respectful' of Susan to run to Namor and Atlantis when ever she has a problem with Reed. I don't think it's 'respectful' to use another man as a cudgel against your husband to get his attention. And I definitely don't think dressing Franklin in green scale speedoes around Reed was "respectful." Sue knows better than to say anything to Namor, given her actions and her desires.
That's not to say, I don't applaud Sue actively working to make sure Reed doesn't take her for granted, but the idea that Namor is the one who is "disrespectful" in this triangle is ludricrous.
Showed zero interest? Sue was the one who leapt in front of Reed for the opportunity to deal with Namor. Sue was the one who was freezing out Emma, because Namor was paying more attention to Emma and the X-Men. And the 'limit' that Namor crossed had nothing to do with him flirting with her, and had everything to do with Namor NOT dancing attendance on her properly in her mind. Hickman had their relationship right, but it was all about the power dynamic between the two, and how they used each other, not about 'respecting' Sue's choice of Reed. TBH, I wonder how much of that dark sub-text Hickman intended.
