Thissss ^ a woman who loves you will work SO HARD to respect you. She will be paranoid of letting a different guy gets near her cause she’s consumed by the worries of losing you. BUT she is young, she seems like she’s enjoying the attention and she’s not mature nor strong enough to resist it. She is not evil, she is not doing it on purpose, she’s just enjoying herself and is not concerned about you. Trying to be immature and get back at her by forcing yourself to flirt with other girls puts you in her frame (unless you genuinely wanna flirt then that’s a different thing). Talk to her but if you felt like she keeps doing it, then you can’t really keep guilting her into respecting you, you have to earn respect not force it out of her. By the end of the day, you have to NEVER fear losing her. If you are worried about losing her then you WILL lose her.
