I am sitting here wondering if I should "pop" the question to my current girlfriend. We have been together for sometime now and we are pretty serious... I even moved from Chicago to here for her. I can't help to admit that living in "sin city" can cause me to even wonder with my eyes.. But- I'm a male.. I don't even think about cheating or anything like that- I just wonder if she is the "ONE".. How does one know that???
