What is why does he want to get me pregnant so fast?

There could be various reasons why someone might want to have a child quickly. It's important to have a conversation with your partner to understand their specific motivations. However, some general reasons might include:

1. Strong Desire for Parenthood: Some people have a strong desire to become parents and start a family as soon as possible.

2. Biological Clock: Concerns about age and fertility can sometimes lead to a sense of urgency. This can be relevant for both men and women, although it's often discussed more about women's fertility.

3. Relationship Commitment: For some, having a child is seen as a way to deepen the commitment in a relationship or take the relationship to the next level.

4. Cultural or Family Pressure: In some cultures or families, there is a strong expectation to have children, which can create pressure to start a family sooner rather than later.

5. Personal Goals or Timing: Some have personal or career goals that align better with having children at a specific point in their lives.

6. Emotional or Psychological Reasons: For some, becoming a parent might be perceived as a way to fulfill emotional needs or to address feelings of loneliness or insecurity.

7. Financial or Practical Reasons: Some may feel financially secure and ready to support a child and thus might want to start a family quickly.

Talking openly with your partner will help you understand his perspective and give both of you a chance to share your thoughts and feelings about starting a family. It's crucial to ensure that both partners are ready and willing to take this significant step together.
