I still need help. I really want to take this trip but it falls on my daughter's first birthday. I can take her but it would be difficult without her father helping me. he always wanted to come to where I go and I can get him a ticket and a room but he doesn't want to even look at me. so, I want to go but yeah. also I know celebrate her birthday early and she won't remember me being there but I will. Idk what to do. please help me.
