I went to dinner with my bf and baby last night at my bfs job also my bf invited his friend and his little family . So were having such a nice dinner talking and laughing nd out of no where I server that works there comes up to the table and stars talkin to my bf . My bf got so nervous because she was flirting and I not once while she was there did she acknowledge the fact that he was with his family and his friends family . She didn't even tell us to enjoy our food 😑. Idk I got super upset . I trust my bf I know he adores me but idk why girls have to be so rude 😒
