If you attend therapy, ask your therapist for a way that suits your needs/ style as a couple.

You are not his nanny. You are your partner and if he's not going to support you and encourage you to be your best self (IE you wanting to study) then he's not the one for you.

There's no harm in waiting. You're not putting it off completely, just until you have your life together a bit more. There's no rush.

I'm sick and grumpy, that's what.

OK then I think that seeing that everything is legit, you need to cut him some slack. It's not a random aunt that died, it's his mom. And around the holiday period too. His whole life has been turned upside down, he's grieving, he's vulnerable.

Go see your buddy and then see if he reaches out. Maybe just shoot him a message to say you're sorry and that you're still around for him and leave it at that.

Have you actually spoken over the phone/ Facetimed him?

Do you have any proof that he even bought tickets and the accommodation?

Did you see on his social media that his mom really died?

This could the truth, that his mom died. This has not been a great year and it seems a ton of people are dying this month alone. But at the same time, this all seems very cat-fishy.
