“My boyfriend and I broke recently, I've never felt so depressed in my life. I still talk to him now and then, but it really hurts because I want him back so much. I love him with all my heart. Before we broke up he asked me to marry him. I was so shocked I said I'd think about it. He then turned round and left me. How can I get him back? I can't live without him in my life. Please help”.
My advice:
I think you should speak with your boyfriend, and explain him the reason for your answer when he asks you to marry him. You probably would feel afraid at the moment he asked you, but you are sure you love him. Your boyfriend would feel disappointed because he expected you say “yes” immediately. His reaction is normal, but I’m sure he will understand you if you explain him your feelings.
