competition: Best Breakup with an Ex

so my gf of over 8 years leaves the country on a medical mission trip to asia. she calls me from the navy hospital ship she was on to tell me she wants to marry me when she gets back. im so happy about it, i dump $3,000 into fixing up her car to surprise her for her return and our birthday. (we have the same b-day) she comes home the day before our b-day and tells me how much she loves me. the next day at our b-day dinner, she tells me that she cheated on me on that ship, and she has "feelings" for the married guy she cheated with.
now that he is out of the picture, she said she wants me back, but is looking forward to her next mission trip?
