Selfish fiancé

I don’t spend money on myself because I usually rather spend my paycheck on my kids but when I have an eyebrow appointment he later tells me 2 hours before my appointment to reschedule it like very frustrating because I booked this appointment 2 months ago. He always does this to me always wanting everything his way . I don’t even ask for much. Like all I ask is pamper myself once in a while. Sorry just wanted to rant. Don’t have anyone else to talk too . I only talk to my fiancé and my mom and my kids.
