She said that at some point the law will have to allow more than two people to be involved in a child's life, when it benefits and is not harmful to the child.
In the case of Daniel and Karen, he has continued to be a part of Karen and her son's life, but she has regrets about not choosing an anonymous donor.
The visitations have been psychologically confusing for her son, according to Karen. Daniel showers him with material gifts and tells the boy he shouldn't call Karen's partner, "mommy."
The lawsuit was harrowing on Karen, too.
"It was almost two years in and out of court, dealing with horrible emotional stress," she said. "The legal fees could have been my son's education."
Her lawyer said women should rely on the California statute to protect their parenting rights and never enter into private agreements.
"[Daniel] really did become a stalker," said Trabolsi. "He wanted so much to be a part of Karen's life…Whatever his motivation was -- it became such a nightmare for Karen."
"She had such lofty goals – she thought this would be the ultimate gift to her child," said the lawyer. "But it was an idyllic picture that went wrong."
Karen agreed: "It was a beautiful situation that backfired."
