Not feeling excited

april
When I was 10 weeks pregnant, i got home from work to find that my fiancé had moved out and got back with his ex, without a single word to me. A month later he still hasn't said anything to me. I miss him so much. I have tried to be excited about this baby, but it just feels like a reminder of him and all of our future plans that will never come true. I already have two kids, and I don't want them to see my resentment of this baby. How do I get over this and become happy again.
