How do you know if you’re falling out of love?

My husband is the definition of a perfect husband. He’s so kind, and loves me so much. He goes above and beyond.....

But for the past few months I’ve noticed I’ve started to want nothing to do with him. I get annoyed when he calls. I make excuses to leave the dinner table when he’s asking me constantly how I am. I’m disgusted by his belching and farting. I have zero interest in sex with him- id rather watch porn. When he touches me I feel repulsed. When he kisses me I get annoyed. When I say I love him- something doesn’t sit right.

He’s done NOTHING wrong. I feel like an enormously horrible person because it’s not like he deserves any of this.

Please help. We were TTC for 3 years, and have a doctors appt coming up. I can’t tell if this is just depression or if I’m actually shifting in my feelings. Either way I know I need to pause TTC- I just don’t know how to have the conversation. Or what I would even say.
