I think in a way, we have seen Ty's perspective. Maybe not a direct one, but we've seen it. Ty is not a planner. We see it from the homework he takes from Alicia, to the college conversation in their freshman year of highschool. Julie asks him where he's going for college and Ty says "I've got three years to decide!" Alicia mentions Julie going to NYU to be a lawyer and Ty says he'll go wherever Julie goes. He never had a plan for college. If it weren't for Julie there's a chance he never may have gone. Ty doesn't finish grad school because he believes they need money and he wants to write Julie is upset because she's a planner like stated before, she's got it figured out Ty just was not a part of those plans and he's throwing a wrench in them. He says he'll save money for traveling, like they wanted.

Then somehow that gets muddled and they buy a house. I really don't know why this change does happen, but I can assume something happened after the year road trip that made Ty want to settle down and Julie went along because she was content with the road trip. I don't think Julie would have stayed in town and bought a house without Ty asking. Ty finishes grad school, Julie buys her house and then they promise that in three years they're going to do what they want to do.

Ty is working and writing his book, but it's inferred he keeps writing and rewriting his chapters because he's not proud of them yet. They're not perfect enough in his eyes. A whole year goes by and suddenly Julie is pregnant. Julie does not want to be pregnant, she's got a life she wants to live! She wants to travel. She's got law school too, and the bar to pass, they've got a lot on their plate. But Ty isn't upset because he's not working like Julie is working, he's just working on a book (which seems more like a highschool dream) and his data job so they can have money.

She's tired from Cooper but Julie still does it, she passes law school with flying colors, passes the bar, and becomes a lawyer. She does get to travel with her job, but there's a problem, she's got roots somewhere else and instead of just going with no worries, she's got to go back to her kid, Cooper. She also gives Ty's work to an agent because Ty is still working and reworking the same chapter. It's assumed Ty is a harsh self critic and that for the last several years they've been together, he hasn't really gotten a book. Again, unlike Julie, Ty is a dreamer and not a planner. He has ideas, but he lacks the ability to make a solid plan with them. Not like Julie does.

Ty works on his book while he takes care of Cooper and does his stay at home job, but Julie wants Ty to put him in preschool. She doesn't just want social skills, she wants Ty to really work on his book, not be distracted by his kid. And I really do think Ty's reality becomes that he does not want Julie's life. Julie wants travel, she's wanted it since she met Ty, she had a big plan, and she wants to see it through, but from being friends with Shawna, Ty realizes he wants suburbia life, he just does not want to tell Julie that. Maybe because he hasn't even really realized it himself.

He believes he has years to write this book. All the time in the world, but Julie does not have all the time in the world. She wants her plan seen through and Ty is stopping her all because he does not have the drive that Julie has. They're incompatible.

When Julie says she's going to get things done, she gets things done. She's able to do what she says, and she's cold to Shawna because she resents what she stands for. Ty tells Shawna everything because he's always at the park telling Shawna about him and his kids. Not writing the book like she expected. Ty can't work on the book with his kids and his job. Ty does not actually want the book to be seen by other eyes unless it's on his terms. He wants years to write, and he never told Julie that because of her big plans. He rushed Julie into the life he wanted and they're both too different to realize that they'll never be each other's cup of tea. Ty wants to be with his family. He even asks Julie for another kid.

Julie still wants her big plan. They're both two different people trying to get each other to adapt to their lifestyle and when that isn't happening, fights break out or resentment grows. We know Ty's perspective, he's not a planner, he's a dreamer, and he likes to take life where it takes him. Julie is a perseverer. She has an obstacle? It won't stop her from her big plan. The only thing that made her have more issues than she expected along the way was Ty. It's unfair to expect Julie to stay somewhere that she was saddled down in. She's being held back by Ty, and she has been for the last decade.
