Looking for a romance book FMC with complicated older sister relationship
Hello everyone,
I am looking for a romance book (maybe has secret pregnancy I read a lot of those) in which the FMC has an older sister who took care of her in her childhood-teen years and then "abandoned" her to get married/ because she fell in love. The older sister and her communicate via phone during the book because the sister lives far, the FMC feels that she was such a burden on her older sister as a child, and tries to be independent in the present and she mentions it frequently in her inner dialogue *but the older sister never saw her that way*.
They have a phone call in which the FMC says something (I recall she maybe tells her she got married or got pregnant pretty soon) and the sister flies to see her impromptu because she is concerned. They meet in a public setting I think a restaurant or diner and the FMC says something along the lines of "I always was such a heavy load to you" and the sister begins to ugly cry right then and there and answers with something like "you were never a problem, you were so independent, you tried to do everything yourself" I think she mentions something about her having her 1st period and prom... (maybe I am hallucinating).
During this conversation the FMC is kind of "out of it" and doesn't understand why her sister is crying, each of them is with their significant other and the men see that they aren't getting anywhere and decide to meet in private in the FMC or MMC house for breakfast/brunch...
-I think the title has something to do with her being "too much-unlovable-having excess baggage".
-I remember the cover being blueish-purple (but maybe I am totally off base)
Thank you in advance!!!
