AIBU to be rather annoyed?
I started an online business venture about 8 weeks ago and have had better than expected success so far (made about £500 in the first full month and it's growing!). I won't go into too much detail as outing but think along the lines of social media/shopping/etc.
It's a relatively niche area of which I have some experience with the target audience etc. I started it to help subsidise my maternity pay.
An immediate family member has basically copied and pasted my entire idea and is now running a virtually identical business, competing for pretty much the same customers! They have a full time job and so have said it is just a hobby for them.
Not sure if I'm overreacting or how to handle? They kept it quiet for the first couple of weeks as they were scared I'd be upset(!).
