My son is 3 months old, my sons father decided when I was 4 months preggo to go back to his other BM, now he was MIA during pregnancy and stuff. So he started coming around again when the baby was a month old and we've been getting along. Well I just found out his other BM is pregnant again now too! Like about to pop pregnant, which means we were pregnant at the same time smh. My emotions are so all over the place, and I'm so hurt and I really loved him. I'm so stressed I feel physically sick....
