well i don't think there's anythign wrong with the fact that they haven't mentioned the baby. expect the made obvious reference to the baby with the paternity test blast this episode. obviously Blair or Louis hasn't forgotten she's pregannt
But i do enjoy that this baby is not being mentioned every second of everyday. it's not an overpowering thing on Blair. I like that she can take her mind off the baby and focus on herself and her friends for a moment. This shower had nothing to do with the baby. It was about the wedding and her friends so i don't see why it was necessary to bring up the baby.
and Blair didn't casually break up with Louis as you guys are putting it. She said she needed time to think about the 'future' of their relation. Key word here 'future' meaning she aspires to one for their relationship. and just because somebody is pregnant doesn't mean they can't take time off to think about their relationship if the relationship is not working. Being pregnant with Louis's potential child doesn't mean she has to stick it out with Louis forever. She still has a choice as a person. this baby doesn't rule her life. and this episode clearly shows Blair has other things to focus on besides thins baby. if the relationship doesn't work. it's not the end of the world. many people are single parents, co-parents and not spouses. Well tbh i think she did the grown up thing this episode andd several times Blair kept touching her stomach affectionately. it's clearly giving hints she didn't forget about the baby.
i don't understand why she can't ask to take time to think about the relationship just cause she's pregnant? she's still Blair Waldorf, whether or not there's a baby in between she still has a choice to make for herself and everything is not about the baby. she can't just care about this baby and forget about herself.
