how would you feel seeing this message 😔

so my fiances phone went off and I checked it as he was out and he doesn't mind just incase it's family that need something or whatever and generally I'm better at replying to them as he forgets. but anyways it was his sister and since he never replies to texts(always uses fb or calls them)there was a whole lot there and I saw my name so obviously I look and if was a message from a while ago talking about how he met someone (me) and described me to her.....i cried I'm very insecure about my body and this just really stung. I get that it was along time ago now that he said it but it still really stings. how would you feel? picture down the bottom is of me for reference I do have a little more weight than what it looks like in the picture but on the whole that's how I have always looked. do I need to lose weight? 😔😢
