Oh yeah, SmirnoffIsTasty? Uhmmm . . . listen to me hon', it would make sense what you are saying had you jilted this supposed psycho gf since. Don't you think? So, you use her to your silly pleasure of always having a trophy even if you didn't like its look? So even if the trophy was ugly and you did not like it, but just the mere fact that it was a trophy, it was good enough for you? So you're shopping around whilst pretending you can endure it? And then when you are done shopping and found your new trophy rather more appealing to you, then you abandon the ugly one? Oh my! Goooooooooooooooood! It never tastes more delicious; does it?
Hon', it takes two and you are not relieved of the duties and obligation you owed her. That is why it will come back to bounce on you . . . 'cuz your nature will not cease overnight. It's called honey moon period now. Let's see what past the honey moon will be . . . if it will continue to conceal your saddening nature. 🙂
At least even if you claim you were not meant for the other, you should apologise to her for your conduct. Instead, you continue to praise yourself and lay all blame upon her? As the saying goes, pride goes before a fall. 🙂
Need I state this is simply my expressed opinion? I did not and do not claim it is some divine truth. 🙂
