It might mean that your ex boyfriend continues to have emotional attachments to you and that he longs to develop something new with you, like a relationship or a life together. However, dreams are not proof of true love, and they do not determine your destiny. You are free to make your own choices about this relationship regardless of your ex's dreams.
No, dreams like this mean that you two think alot alike.
The question is not entirely clear. A dream about HAVING the ex boyfriend's baby would be different from dreaming about a baby the ex boyfriend had by someone else.
Dreams are about the dreamer, so this dream expresses the boyfriend's emotions in some way. Depending on the emotional tone of the dream, it might suggest a desire to develop a relationship or a fear of responsibility and being tied down. Alternatively, the "baby" could be a metaphor of some task or project the boyfriend is developing on his own. For more examples and discussion of baby and pregnancy dreams, see the attached link.
Vivid, outrageous and strange dreams are par for the course during pregnancy. Dreams of having the baby are perfectly natural and expected, since delivery is the desired outcome. The cause in nothing more than the constantly changing hormones of pregnancy.
you still love her
What do you mean? Do you mean you dream about having a boyfriend? If so, it probably means you want a boyfriend right now, you want to be in love with someone. I have had a couple dreams about different guys I had crushes on. At first, I thought it meant that we were meant to be together. But then I realized that it was just my brain wondering what it would be like if we were together. If they are happy dreams, it doesn't necessarily mean that much, continue to think about what ever you are thinking about to make yourself happy from those dreams. However, if they are sad or dark dreams, try to think about other things for a while.

This simply means that your boyfriend is on your mind. It is perfectly natural to dream about a loved one. The dreams do NOT mean that the boyfriend is thinking of you; dreams only illustrate the dreamer's own thoughts and feelings. It means your unconscious mind is fixating on your boyfriend. You are possibly obsessed, don't worry.
Not a lot
The dreams reflect the dreamer's own emotions. There may be difficulties between the dreamer and the boyfriend that the dreamer is trying to overlook, but which cause sadness in these dreams.
It means she dreamt of marrying her boyfriend. Nothing more.
I've heard dreams are your subconscious trying to tell you something. Perhaps you still have feelings for your ex? Maybe a unresolved conflict? or just pure coincidence.
