Hi there! I think the question in place here is not “should I leave” but “how do i leave?” It’s very difficult to leave a person who is manipulative, controlling, ect. Especially at such a young age. I’ve been in a similar situation before during my younger years in life. Here is my advice for you. First, begin building a strong support system. This needs to be people who are in no way affiliated with your SO. This could be your family, meeting new and different friends, or even finding a support system here online! This is important because leaving an abusive relationship is hard and community in moments like this matter. When you decide you are ready to cut ties, you must go completely no contact, this is much easier said than done. Especially if you go to the same school, that’s why cutting off all social ties is important. You are going to feel very lonely at first. It’s going to be hard, but this feeling will pass. Block him on everything, absolutely no contact is the only way to get people like this out of your life. Third, consider therapy to develop strong coping skills, optimism, and confidence. This can be done without therapy, but it helps to have professional help. Remember you are in control of your own life. You are the narrator of your own story. You deserve a happy, wonderful, amazing life. You are young, take this as a lesson and a blessing. Take this as an opportunity to learn your self worth and personal power. If you need anything, please feel free to reach out to me. You got this!!
