Do you believe that guys can love a fat girl

So I’m fat and I’ve never had a boyfriend or anything. This might be because I’m fat and they think I’m disgusting or it might be my own fault since I never make any effort to speak to guys or anything like I’ve probably spoke to 1 guy in my whole life. But ive been fat all my life and my family have always said to me no one will ever love me because I’m so fat and no man will ever want a fat girl. Is this true? It seems like it is because I’m 19 and no guy has ever wanted to speak to me or came up to me like they do thin girls?
