I absolutely hate staying alone. What would you do?

My fiancé has a bachelor party this weekend for a high school friend. The location is 2.5 hours from where my fiancé grew up and about 4.5 from us We’re 3 hours from where my fiancé grew up.

I kind of assumed I’d go home for the weekend and see my mom. Last time we were home my SIL brought up seeing us in a few weeks(her husband is also invited to the bachelor party). My fiancé immediately goes “I’ve got xyz bachelor party I’m not coming home” then my SIL says “oh I thought (me) would be coming home for the weekend” and my fiancé goes “she’s probably staying at the apartment”

I map the route and from our apartment and all 3 suggested route take him through a state that’s not where we grew up. I bring up how the map says he’s going through XYZ and he tells me he found a route going through the state we grew up in on a highway we always take to get home. Says it’s only 8 minutes longer and he’s going that route because he knows it best. I cannot find that route and adding a stop in our home state to get it to go that route adds an extra hour on.

He’s refusing to take time off to go to the bachelor party so his original plan was to leave around 7 pm Friday and get there around midnight. Then he changed it to “I’ve got lots of work to do maybe I’ll go up Saturday instead” the last idea he had was leaving tonight to go to his mom and work from home tomorrow and head up after. Seems like the best idea because it’s a shorter drive from his moms and I could also head home because I WFH. He has not brought up leaving tonight so I think that’s out.

I don’t really want to stay here the weekend. I have no friends because we moved recently and I don’t currently have a car so my only option is sit in the apartment 95% of the day and go for a short walk to break up the day. I also have fear/anxiety over staying alone. I stay alone when I have to but I literally wake up every 20 minutes in a panic throughout the night.

Idk what to do. My fiancé is the type to do what I want but complain after about doing it. Like tell me if I want to go home he’ll meet my mom somewhere or drop me at home but then make subtle comments about how late he’s going to get to the bachelor party. He eventually gets over it.

What would you do? My mom doesn’t want me being alone for the weekend and has offered to meet my fiancé at anytime of the day on Friday or Saturday morning to get me and also offered to meet him Sunday to drop me off. Ok
