I'm Depressed

I'm single again and my boyfriend dumped me because of my weight 270lbs. I'm 5'3. I understand he wants me to be healthy but he said he would break up with me if I didn't. I caught him with another girl. That's all I'm going to say. 😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭😭

We've been together for two years!
