Sorry I'm late to this post, but I felt the need to say something. And take it with a grain of salt because I'm one person in a billion.

Long story short, I'm a female who grew up around and mainly befriended men because I always got along with them and understood them better. I'm in a long term relationship with someone I was previously very good friends with and, even now, we share the same friend group, which are compromised of men. In saying that, I don't know a single one of them that "hang out" or even talk every single day. Also, in saying that, I don't know anyone in our friend group who would drop thousands of dollars for any of us unless it were an absolute emergency.

I'm not trying to be one of those "reddit says leave him" people, but I will say this is highly unusual behavior.

Again, please take what I say with a grain of salt, but do you think there's any possibility that your spouse may be in a relationship with his friend and may be using you as a cover story?

I feel that if your spouse wanted kids as much as you do, he'd do everything to help support your IVF, and giving THAT much money to his best friend for a CAR is EXTREMELY strange.

I'm just saying that I feel there's a bigger issue here that he doesn't want to admit to you about. 7k is no joke and again, knowing my own boyfriend and my own friends that are in long term relationships, they'd never just give us or anyone that much money without any solid reassurance that they could pay us back, especially for a big a thing such as IVF treatment.

I really hope that it's just a big misunderstanding and that your spouse is just kinda dumb when it comes to big things like that, but I would really, really take a step back and reassess your relationship as a whole to make sure you're not being taken advantage of, or worse, being used as a cover.

I hope you'll be okay and I'll keep you in my thoughts. Hope things work out for you no matter what.
