I am so confused

Can someone explain because I am so confused. He is usually super busy and the last thing I heard from him was “babyyy” so I don’t think I did anything wrong? Theres been some days where we both get super busy and we barely talk but this time around I’m not sure what is going on. Am i overthinking things or??? My bf is the type to let me know if I do something that upsets him but he didn’t say anything. Should I just let him reach out to me? #textswithmybf #help😭 #response #confused
