Everything changes after baby! 90 Day Fiancé stars Steven and Olga are the youngest couple on Season 6, and they’re definitely facing the biggest struggle. The 20-year-olds went from having a summer fling in Ocean City, MD while Olga was on vacation from Russia and they found out that Olga was pregnant after only about a month of dating — and they learned the news right before she was supposed to go back home. Now, in a sneak peek for this week’s episode, Steven is in Russia with Olga and he isn’t happy with the fact that it seems like their relationship drastically changed in the two weeks that Olga gave birth to their son Richie via C-section.

“Okay Olga, I’ve had a lot of time to think,” Steven said as Olga breastfed their son. “Remember in Ocean City, you used to be so excited to see me. I would go to work, you’d run up and give me a hug immediately. Then, when you left, that was very hard for us, but you still missed me all the time. Once you saw me getting off the train, you were so excited — just like Ocean City was. But everything changed. Now I don’t know why. What happened?”

“How do you suppose, like after operation, I have to be like, [a] super happy person?” Olga asked.

With all the focus on the new baby, Steven is feeling totally unappreciated! Follow the next chapter of the journey Sunday at 8/7c on #90DayFiance. pic.twitter.com/ErC7U17vfi — TLC Network (@TLC) November 30, 2018

Steven said he wasn’t asking Olga to be “super happy,” but he said he felt that Olga wasn’t excited that Steven was visiting her in Russia. “You’re happy that I get the things that you need for the baby, but are you actually happy that I’m here?” Steven asked.

“I’m literally going out and breaking my a– to get your visa done before I leave. You should be appreciated every single thing that I’m doing for you,” he continued.

“Steven doesn’t understand that right now it’s like natural that mom takes care of [the] baby. But he doesn’t wanna listen [to] me and understand,” Olga said in her confessional.

Steven then pointed out that Olga has not said thank you to him for everything that he’s done for her, and he seemed a little jealous that Olga was focusing all of her attention on their baby and not him.

“Our son cannot be the main thing, we have to keep focusing on us as well. We have to put equal time — the kid can’t be before me,” Steven told Olga. “I can’t put the kid before you, we both have to come equally.”
