Yaaa, honestly, this 'i wanted to get pregnant when I was with him, but now that we broke up I don't' is extremely immature sounding.
Getting pregnant and having a baby is not just what you want to do NOW - its what you will have for the rest of your life. No matter what happens or changes, or what feelings or changes you'll go through in life (because you WILL have changes. Lots of them. Everyone does), you will have this child with you to have to be responsible for.
The point is, if you thought you'd be okay with having a child with a person, and then broke up with them 2 weeks later - you're not using good judgement.
