<human>: Hey, I've never really been involved in acting or theatre, but my current girlfriend, of around 1.5 months, is an avid thespian. She just got the lead in my school's upcoming spring play (so happy for her!). She told me, after reading through the script, that she'd have to kiss a guy. Problem is, the guy is her ex-boyfriend.

I know it's acting, but since I'm not involved in acting, it's difficult for me to see it as a character kissing a character instead of my girlfriend kissing her ex-boyfriend.

I was just wondering if anyone had any advice for me as to how I can feel less shitty about this, while still staying supportive to her. Thank you in advance!

Can you condense the text into three sentences or less?
<bot>: Girlfriend is lead of play, has to kiss ex, I'm struggling with not feeling insecure and shitty about it.
