I Don't know if I want a baby anymore

I don't think I want a baby anymore or with him in fact, I feel like I was To busy thinking about what will make him happy and forget about myself sometimes I wish I had listened to my family and friends when it came to him but because I was so stubborn and have so much love for him I could do anything he wanted to keep him happy, anyways the truth is that I don't believe I'm ready for a child. I would like so advice in how to tell my partner?
