My husband's family didn't invite my 9-year-old daughter to their family vacation because she's not "blood" and my husband said that's "fair" and I should leave her with my mom. I have a daughter, Lily, 9, from before I met my husband. Her dad is not in her life. My husband Mark met Lily when she was 4. He proposed to BOTH of us. He said, "Will you both marry me?" Lily still has that video. He adopted her in everything but legally - we couldn't afford the legal fees, but he is DAD. She calls him Dad. He coaches her soccer. We've been married 4 years. We have a son together, Noah, 2. Mark's family does a big beach house every August in Florida. 20 people, all cousins. Lily has gone the last 3 years. She calls it "the best week of the year." This year, his sister who organizes it texted in the family group chat - that I'm NOT in, but Mark is - "This year is BLOOD FAMILY ONLY to keep costs down. So just siblings, spouses, and blood grandkids. Can't accommodate extras this year." Extras. She called my daughter an extra. Mark didn't say anything in the chat. He just told me that night, "So this year Lily will stay with your mom for the beach week. It's just blood this year, to save money." I said, "What do you mean Lily stays with my mom? She IS your daughter. She's gone the last 3 years." He said, "I know, but technically she's not blood, and my sister is paying for the house, she gets to decide. It's not personal, it's just cost. One less kid is one less mouth to feed."
