am i getting cucked?

so gf texted me first today, texted a bit between classes (very little), she said she was going to get groceries when she got home. her replies started getting like really far apart, told me she wanted to do something with me after midterms (in 2 weeks). her last reply was at 930 to which she told me "been doing work and was eating sorry". she didnt answer after this which is weird of her. usually texts me when shes done or at the very least a goodnight before bed. the two options here are
1. she fell asleep while doing work (rarely happens)

2.im getting cucked
