<human>: The girl [F21] that I have been on/off with since 9th grade have been taking our relationship very seriously over the last 1.5 years or so. The progress has truly been great and up until a month or so ago I was looking forward to starting a life together. However, upon waking up one day I realized that I may not be as passionate about things as she is. 

We all hear "find a woman you can bring home to mom" and she really is. She recently met a big chunk of my family and everyone loves her. Quite possibly, everyone besides me. I have been constantly torn between working it out and putting in my final words and moving on.

 I yearn for romance and a strong relationship and always have. 7 years is a long time and both of us have grown/ changed a lot in that time. Is it wrong for me to want to throw a new line into the lake and see what I might catch? For the longest time I thought this girl was the only open door for me so I just kind of settled.

 Lately, I have become a lot more confident in myself which has translated into a want for something new. The real question is, am I a jerk for wanting to throw everything away and start new or, is this completely normal for someone my age? Am I simply growing up?

<bot>: I am still so young. Do I feel wrong for exploring my possibilities or do I feel excited for what life could possibly have in store for me?
