I just don’t know what to do. Advice?

My fiancé proposed to me two days after he was leaving for a post doc position. I was supposed to go with him but I had to get my license first. It was originally a year contact then two. It’s now possibly one because he’s not happy there.

Finally get it and covid hits. I just got my actual license in the mail and my moms been constantly asking when I’m going to be with my fiancé. I currently live at home.

She offered me frequent flyer tickets because they’re expiring or offered my fiancé the chance to come home and take me back with him.

I spoke to him last night and he didn’t wanna come home because he’d have to spend 2 weeks quarantining before he could see anyone then two weeks again coming home. Then tells me he’d love to see me but he’s literally got no time. He wakes up works all day, makes dinner, eats it for 10 minutes while watching tv then works all night, sleeps for 3 hours and does it again. Said even with that schedule he isn’t getting done what needs to be done.

He asked me what I’d do here and I said I’d just hang out(his contract is up in a month so if he doesn’t renew no point in me getting a job to then leave), and he then says he’s pretty frustrated about work so he’d be grumpy a lot of the time and trying to work while I’m watching tv.

My mom brings it up asking if I spoke to him about when I’m going down and she gets super mad when I tell her the above explanation he gave me. Says he’s being selfish and I’ll have gone a year without seeing him in September and now 2. I saw him in November and at Christmas for 2 weeks. My mom feels he’ll stay 2 years regardless of if he’s happy there or not and then she asked me why he bothered to propose to me. After that says “when people ask when your going I’ll just say your not because he doesn’t want you to come” Then tells me she’s done asking and hasn’t spoke to me since.

I want to go because I miss him terribly but I also don’t wanna stress him out. He’s super stressed out and hates what he’s doing and feels like he’s not learning anything.
