What do you ladies think ?

My SO is going to the beach tomorrow with his "friends" and i say it that way bcus he doesn't name them specifically at all . And he says its a father and daughter day so im not invited. And honestly im not happy about that at all and he wants me to relax and have a day off but honestly i just want to spend it as a family day all together but no . Im i supposed to just let him take our daughtrr without me ? I just need to know if how im feeling is wrong (worried/jealous) 😨😰😡
