You've been on my mind ever since high school. Even after hooking up with my current girlfriend of 5 years.
I'm sorry, what should I say to that?
I just wanted to get this off my chest.
If you are not happy with your current relationship, you should not stay in it. It would be better for both of you to do what makes you happy.
The thought never crossed my mind...
it can be hard to think of this when you have been together for so long, but it will be better to break up in the long run if you no longer have feelings for each other.
