For some people, things like writing, or making movies, or even frickin' fantasy league can end up being a monumental time suck. Plus, in this environment wherein a month's delay can get you fans screaming for your head, then...
Ultimately, she thought she couldn't just cut back, or we wouldn't be here...
Who's to say what a "better reason" is? Women have been divorcing men over porn use. Are you really surprised that there are men who expect the same standards out of women?
Sure, there is that implication, but does that make it necessarily true? Does a woman who cries at night over her husband's porn addiction love him any less than a man who gets offended over his wife's obsession with erotica? You can love someone and wish they stop doing things you think is bad for them. We certainly all have our own hang ups.
I can tell you, too, hand on heart, that some of the strongest relationships involve giving up part of who you are in order to make something work. That's something our ancestors have always known. (That patriarchal act of taking a man's name is an example... and for all our rhetoric against it a lot of those relationships worked...) We all don't come pre-cut to fit in with someone we want to love. Sometimes, we have to saw bits of ourselves off. If doing that makes you resent your partner, then you probably should exit the relationship. But if it doesn't, and you find yourself more willing to part with bits of yourself than with the person you love, then you probably belong together. And from the looks of it, Tlaero doesn't seem to resent him for her doing this.
The big secret of love is that it must first begin one-sided. After all, the decision to love comes from you, not the other person. The question is, does the other person love her. And we cannot answer that without knowing him. Heck, we're all here talking about what a big thing Tlaero is doing, but we don't even know what her boring (to us anyway) husband had given up just to be with her.
Doesn't matter. People have given up more, and the decision to do so is entirely hers. To paraphrase a politician who retired early (now there's a self-defining activity if I ever saw one), "nobody goes to their deathbed wishing they spent more time writing erotica".
