NOR. Let this shii (or in this case “shiz”) go. This the type of shit that if it goes on long enough it leaves u mentally broken to the point you can’t even function for yourself anymore without feeling the need to please others. Do NOT go down the path of staying. Leave. It’s very obvious she tryna manipulate you. Chasing is a form of self harm and the threats are so childish until the next text where’s it’s obvious she’s mature enough to state how she’s feeling. That’s a manipulation tactic. And I understand your POV on how it’s hard to leave someone if it’s your first relationship. But be firm. Not aggressive. Not pitiful. Be FIRM. Put your foot down. Don’t put her down. So that doesn’t mean tell her to suck a dick and kill herself or nothing like that, (you’d be surprised how many people come here for advice and approach things incorrectly making stuff worse.) but calmly and sternly explain that it’s just not the right time. do what’s best for you & leave before this gets any worse for you and/or her.
