She doesn't want to have a baby because...
She could never be the good mother that her mother Sally was to her.
Her mother Sally raised Lara all own her own as a single parent and had to work 3 different jobs to do so and she formed a strong bond with Lara. Lara has no brothers or sisters and pretty much lived her entire life with her mother (until recently).
Doesn't anyone think it's a bit selfish that because she couldn't be a mother as good as her own, that she doesn't want to have children and keep her families 'Boyle' name/legacy alive? I mean her own mother can help her raise her children - it seems like an almost perfect setup.
That's my 2 cents.
