Girlfriend Gives Ultimatum During Snowstorm Before New Job

She’s been getting small barbs in before this (we’ve known each other about a month) which makes me feel she’s insecure about us, but we’re supposed to get a massive snowstorm in VA Saturday night through Monday and is very upset I’m not planning on staying with her despite +1 foot of snow being expected during the day. Says she wants me to be “inconvenienced” and this is a “test” of how much I want to be with her (I’m too old for this). Now, the two wild cards are a) I’m starting a new job Monday and very much need to be ready to go and b) not knowing if I’ll be able drive back to my place Sunday (my car is not set up for that kind of snow which doesn’t bother her at all – she says “I’ll figure it out”) given a huge storm is expected with potentially up to 2 feet of snow. Up until this point we’d recently started being exclusive and she’d kept on telling me how much she adored me, how great I was, etc… and then this ultimatum because she “doesn’t want to be alone Sunday during the storm”. Any other weekend I’d love to stay over as it would be a blast but given all the snow and likely how bad the driving conditions are and that I’m starting a new job the next day (she doesn’t seem to care about this) speaks volumes about a power play on her part. Would love to get some thoughts…
