What are your expectations for having children in your second marriage? Are you both on the same page? How do you deal with differences of opinion?
Not wanting to have any more children
You may have made a decision not to have any more children after your divorce or even during your first marriage. If this is something that is still an important issue for you, you will need to discuss this expectation with your date as your relationship becomes more serious.
There are many reasons why someone may not want to have any more children such as not wanting to deal with childbirth, changing diapers and the other demands of having children. You may feel you are happy with the number of children you already have. Do explore this issue yourself independent of dates or partners and understand why you feel the way you do. If you are clear yourself why you feel this way, it will allow you to communicate this more clearly to your date or partner.
If you change your mind, make sure it is something you really want. Having a baby because you think it may save or strengthen a relationship or because your partner wants one are not usually good reasons. Having a child as you probably already know is a big commitment and you need to be completely sure this is something you want.
There is no guarantee that this second relationship will last though we hope it will. You need to understand that you may have to care for this child as well as your current children by yourself if the relationship does not last.
Wanting children but partner does not want kids
If your relationship has gotten serious and you are now discussing your future together, thoughts about having children with this partner usually and should come up. If you find your partner does not want children and they are sure about this, you need to do some soul searching. Can you enter a relationship and put all your energy into it knowing that you will not have any (more) children. You need to be completely honest with yourself even if the answer is one you do not want. That unfulfilled desire for children could jeopardize the relationship down the road and could lead to divorce.
If your date/partner's wish not to have children is due to the previous relationship they had, encourage them to explore their feelings with a professional. You should not however count on your partner changing their mind and the process may be slow. You certainly should not and probably cannot force the other person into choosing to have a child with you.
