I had a girl when I was 21 and I tried for years to have more and it would just never happen. In God's wisdom it was better that I didn't have another with my first husband. It was not long after that he deserted me and I was left to struggle. Several years later i met a new man who became my current husband. As much as I wanted it to happen it never did. The biological clock ticked away and it is no longer going to happen.
From all of this I learned that a secure marriage with some one you love would oh ace made it a lot easier. Being a single mom is tough. The fact that your partner is not interested in marriage is a pretty important issue. Would he always be there or would he take a hike the moment he felt it getting difficult. A baby changes everything.
Even though your biological clock is ticking and you are going to have to focus on getting pregnant if it is going to happen, you might want to think carefully about your situation before jumping in. If he is not committed to you how committed will he be to the that precious human being that you might bring into the world.
Will he still be there when the baby keeps you up all night, or when there are demands on him to provide for the support and nurturing of a child. I would not trade my daughter for anything, but it has not been easy to get her to adulthood.She has always been the joy of my life. I had no idea of the challenges and self-sacrifice it would take to raise a child.
