Custom font class crashes game - c++

Question

I'm using C++ with the SDL2 library to create a game. I'm using the SDL_ttf extension to be able to use ttf fonts and I'm trying to create my own class that would be more effective for multiple texts on the screen. The code I currently have starts out good, then crashes after about 15 seconds of running. I added more text and now it crashes after about 5 or 7 seconds. I'm looking for advice on how to solve this problem. my full Font class is as follows:
Font.h
#pragma once
#include "Graphics.h"
#include <string>
class Font
{
public:
Font(std::string path, SDL_Renderer* renderer);
~Font();
void FreeText();
void LoadText(int size, RGB_COLOR color, std::string text);
void Draw(int x, int y, Graphics& gfx, int size, RGB_COLOR color, std::string text);
private:
int width,height;
TTF_Font* font;
SDL_Texture* mTexture;
SDL_Renderer* renderer;
std::string path;
};
Font.cpp
#include "Font.h"
Font::Font(std::string path, SDL_Renderer* renderer)
:
font(NULL),
mTexture(NULL),
renderer(renderer),
path(path)
{
printf("Font con..\n");
}
Font::~Font()
{
}
void Font::LoadText(int size, RGB_COLOR color, std::string text)
{
font = TTF_OpenFont(path.c_str(), size);
SDL_Color c = {color.RED, color.GREEN, color.BLUE};
SDL_Surface* loadedSurface = TTF_RenderText_Solid(font, text.c_str(), c);
mTexture = SDL_CreateTextureFromSurface(renderer, loadedSurface);
width = loadedSurface->w;
height = loadedSurface->h;
SDL_FreeSurface(loadedSurface);
}
void Font::FreeText()
{
SDL_DestroyTexture(mTexture);
mTexture = NULL;
}
void Font::Draw(int x, int y, Graphics& gfx, int size, RGB_COLOR color, std::string text)
{
FreeText();
LoadText(size, color, text);
SDL_Rect rect = {x, y, width * gfx.GetGameDims().SCALE, height * gfx.GetGameDims().SCALE};
gfx.DrawTexture(mTexture, NULL, &rect);
}
My Graphics class just handles the actual drawing as well as dimensions of the game (screen size, tile size, color struct, gamestates, etc) So when I'm calling gfx.Draw it calls SDL_RenderCopy function.
Within my Game class I have a pointer to my Font class. (its called in my Game constructor) Then font->Draw() is called every frame; which destroys the original SDL_Texture, Loads the new text, then renders it on the screen.
My ultimate goal is to have my font class set up to where I choose the color and size from my draw function. Not sure what to check from this point on..
Any suggestions? Ideas?
This is what I get (which is what I want) but then it crashes.

I've managed to get it working. After searching a little more on SDL_ttf, I realized that in my FreeFont() function I was clearing out the SDL_Texture, however I did nothing with the TTF_Font.
Adding these lines in that function did the trick:
TTF_CloseFont(font);
font = NULL;
