First dates can be a communication minefield.

On the one hand, you want to present the best version of yourself to someone who could potentially be your boyfriend or girlfriend. You want to get past the awkward “ small talk” and figure out whether the two of you are compatible.

But on the other hand, you don’t want to get too invasive. While there’s no set rulebook for how to act on a first date, there are some questions that could give your potential partner the wrong impression. Business Insider spoke to seven relationship experts and found out their least favorite conversation starters, ranging from asking about an ex to bringing up sex too soon.

Here are the seven worst questions to ask on a first date, according to relationship experts:

Why did you and your ex break up?

Bringing up past relationships can also ruin first dates, experts say.

Some people might be curious about why their date broke up with an ex in order to spot potential red flags down the road, New York City-based love coach Susan Winter said. This question is problematic for multiple reasons, however — including the fact your date likely won’t be honest with you.

Plus, what happened in the past isn’t relevant to the date that’s happening right now. While someone may have had a rocky relationship with their last partner, you could bring out a completely different side of them.

“Sometimes we are different versions of ourselves with different people,” Winter told Business Insider. “There are people who bring out the best in us, and there are people who bring out the worst in us.”
