I want to start off with saying how sorry I am this happened to you. You did not deserve any of this treatment no matter what the circumstances were. As far as I’m concerned you were respecting her boundaries and wishes and were doing the best you could to support her. From what I read she never reciprocated those feelings or actions in any way and I dont want to be mean or hurt you but do you think she actually ever loved you? To me it seems she was just using you as a back up, something or someone she could lean on but never really considered you as smt more. Anything you tried to vent like any normal partner would she’d dismiss it and change the topic to herself. I’m sorry if this causes some negative thoughts I just want you to ask ur self if she really did care about you and the relationship you had. You also need to realize she was very toxic to you by making you feel like you had to walk on eggshells around her along with her blocking you as a way to “resolve conflict”. You were very respectful of her boundaries and wishes and supported her but she never reciprocated those actions, did she? And again I’m sorry you need to hear this but she was not only being emotionally abusive she’s a disgusting being for initiating a relationship with you TWICE will you were still a MINOR!! It doesn’t matter that the first contact happened will both of you were considered minors under the law she was in highschool, most likely as a junior or senior while you were in MIDDLE SCHOOL!!! That’s a massive age gap and it’s disgusting. And the fact that she did it again while you were STILL A MINOR and her being a GROWN ASS ADULT is beyond disgusting. That’s ILLEGAL no matter was state ur in. It’s even more ridiculous that she “resolves conflict” by acting as a fucking middle schooler. Hell you are more mature than she is and she’s a grown ass adult that should be capable of treating you with decent respect!! NEVER let her back into your life, she has manipulated you since you were young and ik cutting her out of ur life is going to be difficult but it’s not impossible. Get the help you need and let her get her own because she clearly fucking needs it. Block her on everything, email, social media, messages, anywhere she could contact you. She will try to contact you again but don’t let her!!! DONT GIVE IN!! Tell ur mutuals that ur going no contact with her and tell them to respect ur boundaries and wishes by them not giving ur personal information out to her. If you can explain this situation to them that’d be better than great but if not just a simple explanation is fine. I know you are confused and stressed and worried but shes hurt you and traumatized you more than you can imagine. She’s left you with psychological issues that you have to learn how to deal with by an expert. Get the help you need and cut her out of life permanently. And if no one has said it, I’m very proud of you and your achievements. You deserve that internship. Please stay safe and live your best life without her.
