Help please

I am a 6ft 17 year old girl.  A normal weight for this is about 170. I weigh one 160. I may have a little tum but it's not horrible. I asked my boyfriend if he's happy with the way I looked and if I didn't work out would he like it still. He said he'd prefer if I worked out. And he says I have a tum still. What do I do?
