Oh it was all a big MESS for them
For starters Alex wouldn’t even talk to his mama after she threw his dad out
He decided she was his enemy. And she was aware of the impact of what she had done, but she had left herself no other choice. She made the decision to divorce Stan not because she stopped loving him- but because she knew that all the crimes he committed were for her sake and her son’s. That maybe if she’d never married him, she wouldn’t have made him a criminal. Carla wasn’t insensitive or dumb. She knew why.
She figured either way, she would have to live with some kind of regret- be it that she let her husband screw up her kid, or that she threw away the man who would’ve done -and did- anything for her. So she made that choice, and it still ended badly.
She knew she couldn’t hope to reconnect with her son like she used to. She tried introducing him to other prospective father figures, to no avail. And she knew that nobody would ever replace his daddy. But she tried anyway.
Then they got the news that her ex-husband died in a flaming car wreckage in Oregon. And she couldn’t bear it. She broke down right in front of him.
They went to his funeral- they had to go across the country. It was the first time Lex saw his dad’s twin brother. It just made him cry even more.
They both retreated into themselves. They barely talked, it got to a point that Carla didn’t even try anymore. She was too consumed in her own grief.
Because Carla thought that Stan had done it on purpose.
All because of her.
And one day Alex got a letter. It was from his uncle. He was inviting him to stay in Gravity Falls with him.
Carla almost didn’t let him go- after all, Stanford was a jerk who hated children, wasn’t he? What business did he have trying to connect with her son?
Lex begged to go anyway. It got to a point that he threatened to run away if she didn’t send him herself. She didn’t have the strength to argue, so she conceded, as long as he took a friend with him.
She rationalized, "maybe Stanford has changed a little. Maybe this is his way of dealing with the loss of his brother, by getting to know his son."
She told herself that over and over, praying things were going well in Oregon.
And her son came back so refreshed it was like seeing him as a little baby boy again. He was apologizing!! And saying that he loved her!!! It was like a miracle.
It gave her the strength to start putting their lives back together again.
She started her own business. She got Lex into a higher grade. She dated a little, but then decided she’d rather focus on her son instead. As long as she sent him to his uncle’s place every summer, he didn’t need another father figure.
By and by, she learned to forgive herself a little. It was always going to hurt, but she was going to be strong for her little boy.
Things were going to be ok.
