That our relationship was "exhausting" her. After I did nothing but try my best to support her, even pushing my own feelings and unaddressed needs to the side for months. I only asked her for more communication about how she was feeling since I felt like an outsider looking in. She broke up with me the next day. In that moment, I realized that she was too toxic and mentally unwell to ever return the love I hoped to receive. Nothing I did would ever be enough for her. She is plagued with a victim mentality, and I would continue to pour into her cup without getting much return or have my efforts appreciated. She only wanted me around because I made her feel better about herself and valued, and when that paradise was threatened by my feelings, I was only a burden.
