<human>: We met when we were 17 and dated for 5 years. I think we spent valuable "growing" time together. Growing into our own personalties, style, responsibilities, lifestyle, and goals. It was really fun. We had our fights, but nothing incredibly difficult.

 I started nursing school in 2013. I have to tell you, it was stressful. I was ripped away from my friends (my schedule was/is insane), gained weight, and was depressed. I didn't know how to balance everything. I graduate in May and I can say I have things figured out (but didn't until recently) and I think my boyfriend was frustrated. He was frustrated being around a ball of nerves (I almost failed out of school the semester before last), being around someone who was not confident (25+ weight gain from nursing school), and I was very insecure.

 I think he got exhausted and felt no happiness from the relationship and I understand that. I really do. I guess it is just hard because I finally figured myself out and how to balance school and personal life. I got all A's last semester and since December I have lost 9 pounds. I look great! But it's a little too late, I guess. We broke up on the 31st of December. He said he was finished and we broke up. A few days later he texted me and said "I am not completely done. I am going to spend this next month putting serious thought into our future."

Now, here I am. Lost. Should I not contact him until he contacts me? Should I not go to sleep at night with hope that we will get back together after a month? It is hard. I love him so much. He admitted that he isn't completely done because he see's my potential. I feel like I made our relationship go downhill. I was always sad and never happy. I always snapped. I feel awful. I took one of the most wonderful things in my life and let it fade away with my emotions. I am so lost.

Any advice?

Can you succinctly summarize the text in 1-3 sentences?
