Just wanna share my story.....

I found out on February 15, 2019 that I was pregnant by the guy I was seeing... I was head over heels in love with him. Flew half way across the world back home to be with him. Well as the months went by I got a phone call telling me he had another girl pregnant as well and that my child would have a sibling 3 months older than her... well I continued being polite to him not in a relationship type of way but in a way that showed him I know he messed up but I wanted my child to have her dad around... well my daughter's sister was born on June 12, 2019 and my daughter is due September 21, 2019.... am I wrong for not wanting my child to be around the other child right away?! Or around the other mother?
