Speaking of not taking the things Emir says seriously, the scene at the coffee shop is a perfect example of why u should never take Emir's words to heart.
In 64, when Zeynep was threatening to take away the baby if Emir didn't marry her, in the heat of the moment, Emir said he would raise the baby with Nihan & Zeynep just needs to have it. /
But in 65, after Zeynep saves him, Emir does a complete 180. Now, not only does he say Zeynep can keep/raise the baby in the apartment above the coffee shop, he also gives Zeynep the ultimate gift: Her own business. The means to support herself.
This is a HUGE deal. Not even Kemal thought to give her such a gift. Half of Zeynep's struggles are caused by the fact that she's forced to be completely dependent on other people because of the mistakes she made. She's tried to hold down a job, but because of all the craziness going on around her (mostly thanks to Emir) she keeps losing them. Emir knows now that she's not a freeloader. She wants to be independent, make her own living, & not just be his mistress -- so he gave her what she wanted. As a business owner, she's not beholden to anyone's schedule. She can hire staffers and run the business while raising Poyraz. And that is a huuuuuge gift coming from Emir -- someone who thrives off of making people depend on him. (I know that he could potentially take it away, but the gesture -- even that he thought of it at all -- is still huge).
And as for letting her "keep" the baby in her belly -- I don't think he ever intended on taking it away. When he told Zeynep that he would raise the baby with Nihan, he already knew she was planning on dumping Hakan. So the reason he's backing down on that is because he never planned on doing that at all. He was just trying to hurt Zeynep in the moment for trying to give him an ultimatum. (He's not stupid and he knows Nihan would NEVER raise Zeynep's baby with him.)
As much as an a-hole as Emir is, you can see him ~trying~ to make Zeynep as happy as he can here w/o giving up his obsession, which means something. But we all know she deserves more. She deserves for him to finally leave Nihan and commit to her.
