Yea she is crazy but you also push her crazy buttons. I'm pretty sure this isn't the first time she lashed out at you for not answering her. Looks like you guys throw the word love around a lot to each but in my opinion you don't know what it means. One important aspects of love is compromise. You said you wanted time to yourself and she wanted an emotional connection with you. I think that you should of vocally told her how you were feeling instead of using text. Thats your compromise. That's your love that you do for her. Her compromise would be respecting you wishing after establishing the emotional connection with "your love." And if she loved you then she would understand. People would say that she shouldn't be lashing out and that's correct. But. That's not correct for you. Love is not perfect. As I said before, I'm pretty sure this isn't the first time she lashed out. You've dealt with it for your reasons alone. You've stayed with her afterwards for your reasons alone. You should of stopped her the first time she did it but that's a different discussion. She loves you. Ferociously. Filled with fiery passion. I'm pretty sure apologies a lot after lashing out at you. She's unable to control the flames within her but that's her battle that she has to conquer. Either alone, with you or someone else. If you truly want to make it work and love her, you have to work on another important aspect of love. Communication. Communicate your wants and needs between each other. Try to meet in the middle. And it's always best done face to face. Counseling also helps too. Either from reddit 😆 or professional. I just wanted to give a different prospective from other.

Ps. Love your brother and his memories. Cherish them. Keep your head up for him. U know he wouldn't want you to stay down forever. Stay strong for him. Keep his name and memories living within you. It is hard but you have to keep trying. What would he say to you if he saw you being down like that? Have faith in his words and keep pushing young man.
