Single Trite Female

In February, I discovered my girlfriend was cheating on me with her millionaire ex. I told him, and he told her to beat it. She tried to patch things up with him, but couldn't, and came back to me two months ago, saying she loves me and wants to marry me. But I've started catching her in lies again. For example, she said she'd be studying at home, but she wasn't answering her phone (rare for her). I dropped by at 10, and she wasn't there. This was just two days after she took me to dinner and told me, "One day the world will be ours!" What gives? What alternatives do I have besides ending it?

Good thing you're not on the parole board. You'd only need to hear a guy talk like a motivational poster -- "Good is its own reward!" "Tomorrow is a brand new day!" -- and you'd campaign for the release of some serial killer who kept all his dates in jars in his basement. Of course you want to believe your girlfriend's "One day the world will be ours!" but she has yet to show herself to be ethical, and it's wildly unlikely she'll become ethical now. What alternatives do you have besides ending it? Well, you could stick around and be lied to, cheated on, and placated with aphorisms: "Our love is here to stay!" (As long as you don't call or come by after 10.) "Our love is like a rose!" Well, okay, we'll give her that one -- in that it has something in common with getting stuck with a thorn, coming down with necrotizing fasciitis, and losing an arm.
