Re: I don't want to get pregnant
It was 2.5 years after I was married before I felt ready to have and raise a child. It is a very real responsibility -- it's not just about having a baby, it's about bringing a human being into the world and guiding her/him forever. I just wasn't ready to dedicate my life to that, and I knew I did not want to half-ass motherhood. I am too aware of the consequences.
Some women are able to be amazing moms, amazing students, and amazing workers all at once. I know myself, and I know that I just would not be able to succeed in a satisfactory manner if I was trying to do it all at once. I really wanted to become established in my career -- even get to an administrative position -- and then consider motherhood when I felt ready to dedicate myself to it. I'm glad it worked out the way it did. I feel satisfied with my career; I know I can come back to it if/when I'm ready, but I am excited and looking forward to my new path. I don't feel like I am missing out on anything by choosing motherhood, and I think a few years ago it would've felt that way.
You need to be ready for motherhood. It is the most important and consequential job you will ever have. You have to be ready to dedicate yourself to it. That doesn't mean you can't do other things as a mother -- you should! But you also have to be realistic about what you can do well and what you are willing to sacrifice.
I have a partner who has supported me throughout all my decisions regarding my career and motherhood. He knew I wanted to be a mother and he waited until I was ready. I think he wanted to be a father before I was ready to be a mother, but he also valued our time together as just a couple, and helped me to transition to my new life. Your life will be very difficult if your partner cannot understand your perspective. You won't agree on everything; but you should be able to agree on critical life choices and you certainly should be able to understand each other's perspective. If that is not the case, you need to really think about whether this is the right choice for you.
