I was in a similar situation years back. I convinced her to break up with her boyfriend. Never regreted it. Had to avoid him like the plague though. And too be fair their relationship wasn't all that deep. She was dating him because her friends told her to. I say you need to learn of what kind of relationship she has with her boyfriend before making a decision.
"Now, a fun game should always be easy to understand - you should be able to take one look at it and know what you have to do straight away. It should be so well constructed that you can tell at a glance what your goal is and, even if you don’t succeed, you’ll blame yourself rather than the game. Moreover, the people standing around watching the game have also got to be able to enjoy it." - Shiggy
