Girls, is this bitchy, would you be offended? 10 points?

am i overreacting or do you think it is justified? im going on holiday and i was talking to my bro's girlfriend and i was like im going to wear this really nice bikini. she was like oh you shouldnt wear a bikini, it wont make you feel confident, you should just wear a swimsuit. i havent got an amazing body, it's pretty average and im not ashamed of it. i have a bit of a belly, but i mean there are bikini's that flatter stomachs. i would to look good and feel good about myself and not feel like i have to cover up because im a bit overweight. i dont believe you have to be a supermodel to wear a bikini. i havent got like an amazing body, but its not terrible. i have slim legs and arms and big boobs. she hasnt got an amazing figure herself, worse than mine, sounds mean but being honest and i know she's self conscious about it. i am offended, should i be? mature answers please
