I don't fully agree with you here, but I understand where you're coming from. I agree, quite adamantly, that Max and Liz were not together after Destiny, and they weren't even together throughout a lot of Season 2, so that in no way justifies Liz as "cheating" on Max, of Max "cheating" on Liz.~*Sonia E.*~ wrote:
Liz told Sean in Departure that "Max Evans broke my heart," then 3 months later not only is she back together with Max, but she is helping him find his son. Max and Liz were not together when Max slept with Tess, so how could Liz's heart have been broken? The same thing with Max when he caught Liz and Kyle in bed together, why was he upset? Liz had broken up with Max in Destiny so he had no reason to be heartbroken.
However, I can understand why they'd be heartbroken. Despite the fact that they weren't together (in EOTW or ITLITB), they obviously still loved each other and just lost their way or whatever. Stuff happened to pull them apart, but their feelings for each other were still there. So, in that aspect I can understand why they were heartbroken, but they both made mistakes. ....moreso the writers, but who's being technical?...

Anyway...That's my opinion!
