What do you consider too thin for a girl?

Anonymous
so to make my story short my boyfriend thinks that I should put on some weight at the same time I think that actually I need to lose some extra pounds !

I was aneroxic but I recovered now I'm 141 lbs and I'm 5'9'' that's definitely not too thin for me 125 lbs would be perfect

am I really too thin ?
