<human>: Give me a shortened version of the text

I just got out of a fairly intense relationship. We were only together for 6 months but I fell head over heels for this girl. She was my first girlfriend, first girl I had sex with, and the first girl I have ever fallen in love with. Despite the fact that I am only 19 and she is a 27 year old single mother I thought we would be together for a long time. I was wrong. She broke up with me because after the new relationship excitement began to die down she realized that I was too young for her. She told me that she was (and still is) *madly* in love with me, but that she can't wait around for me to become the man she needs and the father her child needs. It breaks my heart; but she's right.

We broke up about 3 weeks ago. I'm not very bitter about the breakup. I'll admit she is right; I am not ready to be a father. My issue is that I fell much harder for this girl than even I realized. Now that she is no longer a part of my life I am left feeling very depressed and deeply lonely. I know that time, exercise, and maybe a bit of weed will help alleviate my depression. I am not sure what will help me get past the crushing feelings of loneliness besides spending time with her. 

I'm sure this experience is pretty universal. How many people really spend the rest of their lives with their first love? Basically none. How can I stop analyzing my every action for where I went wrong, how I can I stop fixating on her as the source of my happiness, and how I can ultimately move on from this relationship? It may be melodramatic but I feel like I will never love anyone like I love her.
<bot>: We fell in love, she realized it wasn't going to work, I am heartbroken. What do I do?
