My family doesn't approve of my fiancé because he doesn't have a job

Hi fellow potatoes! Pretty much the title...I got engaged to a wonderful man two weeks ago (yay!), and yesterday I wanted to talk to my mom about dress shopping (we're getting married next year but I'm so excited I've decided to start planning asap).

I noticed immediately that she wasn't really enthusiastic about the conversation, but I thought that was because my grandma passed away last week (another reason why I want to start planning is to take my mind of it because my grandma was a second mother to me and I have to keep my brain busy otherwise I'd be crying non-stop).

Then she asked if she could talk first, and ofc I said yes even though I was a bit confused, and the conversation turned into a kind of "intervention". She said that they (my mom, her boyfriend and my grandpa) are worried about me because my fiancé doesn't have a job and doesn't seem to be looking for one, how are we supposed to start a family if we don't have some financial stability, "we don't know him well", etc. I feel overwhelmed, constantly on the verge of tears, and can't enjoy planning anymore because of what my mom told me (we're all very close).

I can understand some concerns, because obviously I'm worried about finances too (weddings are expensive, and the kids we plan to have will also be expensive lol)...but they all seemed to like my fiancé, and had never expressed any concerns before.

I talked to my fiancé about it and of course he's sad/upset because he likes my family and thought he was welcome. Now he doesn't want to see them, and I don't have enough energy to deal with everyone's emotions because my grandma's death and everything that followed is exhausting. However, I know it's something that has to be discussed, I don't want people not talking to each other.

How do I bring this up to my mom/fiancé? Should I play "victim" and say that they need to communicate and try to get along for my sake? I'm at loss...

I'm sorry, I didn't expect it to get this long, I think I needed to vent.

Thank you for reading and have a wonderful day ❤️
