Don't assume anything. Take it as it is.
I moved away from college and tried to cling onto my friends at home and party all the time while neglecting her and after I lost her it really hit home. What I had with her was much more special and I was just not very appreciative and took it for granted. It's definately possible to mature and grow up. I hope that happens for your guy and he will realize this and....come back to you? I wish I could come back to a girl that still cared about me and wanted it to work. I was the one that got dumped and my ex's the one going serious with a new guy for the last three months.
What are you going to do?
Waking up next to a beautiful girl,
Step outside and say hello to my beautiful world.
