I'm so annoyed.. my fiancé doesn't necessarily like my mom, but my mom has been staying in South Carolina for the past few months (we stay in ky) for work and for our spring break next week, she booked us a condo so we can come visit and have a vacation with our daughter before the new baby comes. Well today she lost her job. My fiancé no longer wants to go on this vacation because she'd be staying in the condo with us instead of at her friends house since she isn't going to be living in South Carolina anymore... I'm just hurt and upset that he's throwing a fit when he should be grateful we still have the opportunity to go on a trip being such young parents of soon to be two girls...
