You've decided to chase it down regardless, so reality has to take a back seat to your blind pursuit. Not much we can do there, I hate to admit. Well, as long as you have a motto, reality can take a backseat, I suppose.
You gave us too much information. You gave us enough information that all of our combined experience and expertise says this relationship is a goner...if not soon, eventually. That's why you don't want to hear it. That's why you even need a "motto".
You see, growing and maturing relationships that are destined for the ages don't need tricks for conversation, internet help for "how to things spice up", and pats on the back for NOT hitting your girl for 3 months. (Um....good job on that? *gulp*)
So, I'll at least give you some overall worldview help that may you see your life in a clearer way, and then maybe you can fix this yourself...who knows? Here goes:
There is only ONE thing that will work to ever help any relationship - balance.
- Love God first - this is so you don't think you're the center of the universe and give yourself permission to do whatever you want...like hitting a girl, even when she 'wasn't innocent herself' (whatever you think that's supposed to mean.) You need some accountability outside your own sense of right and wrong. Parents are good for this...God is better. He never goes away.
- Love yourself - this is self love based on paying attention to your higher authority first (see step 1). After that, you have to be comfortable with who you are, where you're going in life, no need to defend it or apologize to people for it, no need for any one specific person to be a part of it either...you and God together pursuing what is your own awesome life. That alone should give you PLENTY to talk about with anyone.
- Love others - notice the third thing isn't love money, career, your own position, it's putting others right up there in importance with yourself.
Calling this girl the love of your life and touting a motto is just your way of not taking responsibility for paying attention to what is going on in your most important relationship. If you need stuff to talk about, get out there and do some selfless things in life. Talk about that.
