My partner changed his mind

Alexis • Tue, Apr 12 • 3 year old Chloe💖 11/15/15 & Jacob 💙 3-5-19

My SO & I both decided we wanted the same thing , more kids, to buy a house etc. I'm on the pill but a few weeks ago we decided I would take my last pill this month & start ttc. After talking to him today he changed his mind about having a baby. It makes me really sad. I really want another baby & now it has me second guessing our relationship.
