"You lied to me"

My daughter is three months. I LOVE her soo much. I officially understand the unconditional love now. Her father and i are not together since December. He wanted his freedom and i walked away didnt even cry about it was HAPPY he wasnt going to stress ME out while pregnant. Once we found out i was pregnant...different story. My doctor told me i was going to need help getting pregnant even tho my period are regular. I was very disappointed and hurt by the news. Was depressed. BUT eventually accepted it and CARRY ON because MAYBE i am might to be a step mom (he has a previous child). I told him what my doctor told me of course we didn't use protection. I dont object the use of condoms either...you know man, "it doesnt feel right" etc. I moved state too to be with him. The ONE time i actually get pregnant by some miracle i am considered a "lair" by him and his family. Idk HOW it happened. I was in shocked. In denial because i believed my doctor. Fast forward. Our daughter is born...three months now. Two days ago. He brought it up AGAIN. Like, i trapped him. I lied to him. How he wants to talk to my doctor with my permission of course to ask him questions about my infertility problem that i thought i had. He brought stress to me again. Mind you he is 34 yr old. Also his mom is in it too. Because from the start when him and i talked...he also accepted our pregnancy. His mom got into his head and he started questioning me again.

Am i not to be trusted because i believe my doctor? Did my doctor lied to me? Like idk HOW to make him and his family MOVE on from this. They suppose to look forward and not back. I did. Our daughter is a blessing. My blessing. I gave him my doctor's name tho.

When him and i were NOT talking. I was 100% happy and stress free.
