Hey Rosie -
The great news is, no matter who is trying to sabotage you, what you put in your mouth is controlled only by you! So let him try to sabotage you...you're onto him and you're not gonna fall for it!
What sort of plan are you following? We most likely have an area for it, so look around and settle in. We also have chat groups by age range, as well as a lot of miscellaneous clubs - all very open and welcoming.
Can't wait to see you around - keep posting!
