Got another job offer

I’ve only worked at my dollar general for two months, within two weeks they made me a keyholder and then within my first month my SM did time card fraud on me so my ASM who I love is transitioning to being SM. Often times I get left to run register all day and will get my half the last hour or two hours into my shift. I know my new SM and her new ASM are working hard to fix the store but I got a job offer to work Thursday, Friday, and Sunday at this super small luxury grocery store working 8 am to 2pm. I feel bad because I want to stay working at dollar general but those are three days of the week I will either have to now ask to have off or either work after my other shifts. I like my new SM as a lot but I don’t know why I feel like I owe her anything when I’ve only known her two months? Should I go for it ?
