Toxic men

I have a question, my man of a year and a half met me with tattoos and I had let him know maybe into 6 months of our relationship that I was going to get more and he said he was going to break up with me if I got more. Now ive put off getting more tattoos but now I have a piece that I want to finish so I went ahead and booked the appointment 4 months from now and now he literally just told me I am single.. ladies what are you doing? Because I’m not backing down and I’m calling his bluff and I’m getting this tattoo. What would be a response to Something like this? What would you do?
