Most Helpful Guy
"guys always suggest loosing weight will solve all of a big girl's problems"
Guys who say this, then say a boob job will solve all of a big girl's problems, maybe a different wardrobe, different hair, etc. What they're saying is: I don't like you. You don't want these guys.
And you will feel worse if these guys if these guys like you after you lose weight, not because there's anything wrong with you, but because you'd be attracting these shallow nitwits.
What to do instead? Be fun and flirty and friendly, watch for those guys who like you NOW for who you are. These guys like you for what you can bring to the relationship *right now*, not for how you could change to make them happy.
