22-Year-Old Stops Financially Supporting Older Sister After Her Latest Pregnancy Announcement
A 22-year-old's unwavering support of her older sister and her 7-month-old son ended when the latter doubled down on her irresponsibility. OP has been supporting her sister Mia and her new nephew ever since the father walked out of their life a week after the baby's birth.
OP propped her sister up until she was ready to stand on her own two feet. Her hope was for Mia to find and hold onto a job that could support her and her baby.
OP's hope was dashed after one phone call from her sister. Mia excitedly told OP she had big news — the defeated younger sister's intuition worked overtime.
Despite her dreadful gut feeling, OP asked Mia what her news was. Mia informed OP that she and her new boyfriend were expecting a child together.
Mia gushed about how nicely her new boyfriend treated her and her baby. She said this new guy was the one, and she couldn't wait to start their family together.
OP didn't have it in her to sugarcoat things for her older sister. She told Mia how unwise it was to have a baby with a man she barely knew.
OP told Mia how unrealistic it was to want to marry a guy just of the fact that he treated her and the baby nicely. Her new boyfriend didn't provide for her or the baby materially.
To drive her point home, OP told Mia she didn't think their relationship would last. Mia would find herself a single mom of two, not to mention how dangerous it was to be pregnant so soon after giving birth.
Mia called OP a fake person who didn't act like how a family is supposed to. She said OP should be as supportive as their mom was.

OP found out that their mom had been egging on Mia's fantasies. She shared stories about how she married her new husband within two months of meeting him.

OP told her sister she would stop supporting her and her baby financially. She said she refused to finance Mia's choice.

OP told her sister she refused to enable her irresponsibility. Mia cried and accused OP of hindering her happiness. Their mom also got upset with OP and how she viewed her sister's pregnancy.

Mia's reliance on OP was bound to end at some point. The arrangement prematurely ended when OP didn't agree with Mia's decision.

OP's statement was pretty perfect. It wasn't insulting, but it was direct. It didn't leave room for any argument despite Mia's attempts to emotionally manipulate OP.

OP needed to be frank with Mia. She shouldn't have to be responsible for another adult's emotions. She already pays for everything, should she also manage Mia's emotions?

If their mom supports this relationship 100%, now is the perfect time to step up and finance Mia's love life.

OP is way too young to be an entire family's ATM.

OP can't pick up the pieces of Mia's life each time she stumbles over her romantic delusions.

If Mia was so sure this guy was the one, shouldn't she expect him to work hard for their family? Was OP supposed to budget for this new boyfriend as well?

OP has given Mia enough grace. She generously supported her and her baby while she recovered from her first pregnancy. OP has done enough.

OP should invest in herself before Mia drags her down with her.

OP has had to grow up faster because of her sister's poor decisions. OP has been a great sister to Mia during her rock-bottom moments.
Now that Mia has found a partner she felt could support her, she has to stop relying on OP's kindness. She and her partner should work diligently to finance the family they couldn't wait to start.
