He tricked her into having a baby with him, then abandoned them financially and emotionally.
Come on now, these are consenting adults. She wasn't a child getting tricked. She was a grown woman who had consensual sex, didn't take birth control or use protection, and choose to take the pregnancy to term.
I wouldn't say "he tricked her into having a baby", but it's not exactly nice to leave someone after a baby was born and not provide any support at all (she had to fight him in the court for child support).
