It's not weird to want that.
And it's also not weird if your girl doesn't want that. Work is tiring af and seeing other people can be exhausting if you feel like shit.
By the time I get done with work, exercise, dinner, take out the trash, shower, it's usually like 8:30-9pm already and I'm tired af and comfy and all I want to do is play some games then read for a bit in bed, get a wank and sleep. Doing stuff with other people is possible, and like with my current gf I try to see her like one weeknight a week but it's not the easiest. I completely understand how someone could not feel up to getting together during the weekdays.
Still, you both gotta try to compromise a bit for each other. I'd talk to her and let her know you'd like to spend more time together and see if she'd be up to hang out during the week like once a week. You can let her know it can be chill and you don't have to go do stuff out after a long workday, but just chill. Play Stardew together at your place or something.
If she's not willing to budge and compromise at all for you and only willing to see you once a week you just gotta decide whether she's worth it or to move on.
