I am tired of talking about Sakura. Let's assume that she only loves Sasuke and she has no respect for herself so she is always going to want to be with Sasuke no matter what. I don't care.
However, the post-canon materials make Sasuke into a piece of human garbage. This ruins his character if you were of the opinion that he was portrayed as generally honorable, which I was.
First the war ends and Sakura makes an advance on him. He accepts this romantic overture without making any kind of commitment at all. He just says he'll see her soon. So he could come back in 2 years, 10 years, or he could never come back. He does nothing to reassure her that he will in fact return in any reasonable amount of time. Sakura will just be waiting around looking like a complete idiot. This is in fact what happens. He takes advantage of Sakura's naivete, her pathetic devotion to him, her lack of self-preservation, and her willingness to suffer on behalf of someone who has done nothing but hurt her. He takes advantage of all of these things to go do whatever he wants whenever he wants with zero commitment attached to himself. It would come off as quite predatory if he actually showed any attraction towards Sakura. I believe he canonically returns within 2 years.
At this point he gets her to give birth to or adopt a child somehow. Then he leaves again, abandoning both wife and child. He does not stay in contact or make any commitment to ever come back. This is also inexcusable because he's abandoning his "family" without providing any financial support or having any kind of presence in their lives. At this point he's gone for 12 straight years without returning at all or contacting them at all.
So Sasuke has created a difficult situation for Sakura and his own child without doing anything to make it easier for them. This is a situation he should not have created if he did not have time for it or if he didn't want to invest time in it. However, he does it anyway. His reasoning for doing this is unclear and frankly baffling. If he was thankful for these bonds that somehow survived his becoming a terrorist and murderer, he would not do this. He would respectfully decline or at the very least use protection.
Realistically, he should just stay away from Sakura. This is someone who he tried to kill and who his best friend used to love. He should view her as an untouchable property for these reasons. He disqualified himself by trying to murder her, and disqualified himself further by taking a mission that means he can't return to Konoha for over a decade. If he wants sex, he can just go see Karin. His actions make no sense and make him look horrible.
But Kishimoto didn't care if it made sense, he only cared about getting Sakura out of the way for NH.
As a result, Sasuke is a piece of s***.
