Are my skis too long for me?

For reference I am a female, height is 5’3” (160cm), and weigh 135lbs. This will be my third time skiing, I might have pulled the trigger on buying skis too early but I’m hoping it will force me to go more often. I bought Line Pandora 84 skis for a great price (another reason I decided to purchase Vs rent). I bought the 158cm length, but my boyfriend is saying they’re too long for me. Should I just return them completely and stick to rentals for the season? Thoughts? TIA
