<human>: Can you summarize the given text in a few sentences?

Today, I (24M) saw a news article titled: "True love after five partners". As a joke, I told my gf (23F) that I didn't have 5 relationships yet (which is true if you only count the serious ones), so I should look for new partners.

Although were together for over a year (and the relationship was off and on 2 years before that), we're very happy together. We live together since the start of this year in a nice apartment and aside from lots of fighting (maybe due to our conflicting personalities), I think we're doing alright and don't see this ending anytime soon.

Lately, I've had some interviews abroad at big companies, and if lucky, I would love to work there. We've already talked this over many times. She wants to move with me if I get the job, which might mean a great dependency on me since it's uncertain if she would be able and willing to pay for an appartment there since she'll probably study or do a job without a degree. Breaking up would probably mean that she would go back to our current country, where our family and friends live.

After telling her about the news article, she told me she wants me to be absolutely certain of our relationship. In order to become more certain, she wants me to date other women (I also told her I wished I had more dating experience (when I was drunk) in order to become even more confident about our relationship). This way, she'll feel more secure when moving with me if I get that job: she'd rather know now that we're not meant to be than find out later.

What is your opinion on this? It feels a bit like cheating, which may cause serious damage to our current relationship due to jealousy, but may be a smart move in the long term.

P.S. Hey honey, if you read this: I love you! ;)
