I sense it is not the right time for you to have a baby - your mind is not in the right attitude for bringing another soul into the world. Examine honestly why you want a child so much to find out why you are having such difficulty.
@badgerwoman Cancerian men can be abusive Jerks. So sorry to hear about what you went through.
Personally I don't like cancer men. Being a cancerian myself they get on my nerves. My Father in law is a cancer and is a jerk. He cheated on my Scorpion mother in law before we lost her to Liver cancer. He was a very abusive husband at the same time manipulative and dark.
