Did you even play the game?
Jesse wants to take Dina back to Jackson because she needs proper care. What you're forgetting is that they don't want to leave Tommy behind. Jesse and Ellie leave to find Tommy.
Jesse reiterates this during Seattle Day 3, which does not take place during a cutscene.
They later hear reports about how a sniper is in the area, who happens to be Tommy. Jesse wants to go in the direction to find Tommy while Ellie still wants to go after Abby. Every returns to the theater later and they're all set to go back to Jackson until Abby shows up and kills Jesse.
Jesse never flip-flopped. He wanted to go back to Jackson, but he didn't want to leave before finding Tommy first.
I am completely aware of what happened but stating what Jessie does plotwise only highlights the flaws in the story.
Leaving an sick and pregnant woman to go after a guy that is on the exact same mission as the main character, sticks out as being contrived.
I doubt anyone would do that, unless they really hated their lover -- even then it's a bit of a stretch. In all the relationships I've been in, if one party abandons the other in a time of stress, the relationship is is almost always over. It's a signal that the person just does not give a shit on a deep level.
But here we have two characters who supposedly loved that person do the exact same thing, with barely any discussion about it.
"She's pregnant" Ellie cries, as Abby is about to slit her throat. At that point I was thinking "Well you pretty much left her to die, what do you care?".
That lack of care Ellie displays towards Dina runs contrary to the plot which tells you that they are in love. Actions make the man (or woman here) as they say.
The flip flopping is seen clearly here in the below Youtube clip. The actors do an excellent job of trying to sell this, but the only explanation that is really given are that Dina has given orders for them to leave. This is also odd as the previous lines of dialogue are Jessie agreeing with Ellie that they need to take her back.
Ellie's explanation -- "I can't just leave Tommy, He's out here because of me"
-- YES but Dina is also, and she's sick and pregnant.?
That doesn't make logical sense. It makes sense in that Ellie is a driven, uncaring little bitch -- But there's no objection or questioning from Jessie here, just blind obedience -- and that is contrived given the circumstances and his relationship with Dina.

E -"Maybe you could take her back?"
J - "She's not going to leave without you"
Then ... Just after ...
J Screw it
E Are you good with leaving Dina by herself?
J Her orders.
So Dina basically has "ordered" Jessie to leave with Ellie, presumably not just screaming "go away!" when she was "throwing up all night".
And Jessie, rather than taking that as just the ramblings of a sick person with a fever, decides that she was acting in a sound mind as is now just fucking off because she said so.
Then when they tell Dina that they are going, she seems to already know and accept this, even though she hasn't been told. Then they leave.
You would at the very least make sure that Dina was in a stable condition.
This all smacks of a writers room filled with people who either don't have children, or are just spitballing ideas without really thinking about the characters.
