I miss my bestfriend

I do feel that, my biggest mistake in marriage is for me not moving on. I mean, I marry my best friend. And I assume that we will become best friend throughout our marriage. And along the way, I fell in love with him. But somehow, after 10 years of marriage, we reached our plateau and this relationship become stagnant.
Maybe, we just tired with each other. Or maybe, I'm just tired. I don't know. I miss the best friend I know in my husband. We used to talk about everything and anything. And now, he prefers talking to his friends about most things. And what hurts most is that, I love my best friend.
During our 2nd year of marriage, I always talk to my husband while he focused on his phone. He just loves his phone so much that I suspected that his phone is his everything. Since then, I start to learn ignoring whatever he's talking.
I guess, this is not entirely his fault. Half of it is my fault too. I used to be like a puppy, always vying for his attention. But as the year progresses, I saw how pointless it is. And this escalates when I see for myself how good he's treating others as compared to me.
In the end of the day, I thought, why bother? Why do I need to vie for his attention when he prefers to giving it elsewhere? So now, from today onwards, I would not be bothered by him. Just hey whatever. And what's the point in impressing my in laws anymore? When in the end of the day, we will not be together and go our separate ways. Maybe I shud start planning on how to send my husband home to his family. Ha ha
