Ladies, who is getting married soon or recently engaged??

Ladies, I am going through crazy times in my life, not sure whom to date anymore... I was recently engaged to my forever love, that is what I thought but we had to break it off cuz he said I was not good enough for him, now I am honestly lost and have no ambition to see anyone anymore, I am so depressed. So I want your advices ladies, how do you guys stay in a relationship for long and especially after marriage??
