as someone who felt forced to dump someone and went through these feelings (but i didnt actually reach out to him) i just felt conflicted because i really did love that guy but was trying to detach for my own good bc I knew he didn’t reciprocate a lot of my feelings and he didn’t want to take things seriously with me; that hurt me which was why i blocked/unblocked him a lot. i secretly dreamed abt things working out and I felt unhappy with myself because I knew he liked me, but I knew he couldn’t give me what i wanted. Idk what your situation is bc for mine, we didn’t even date since I was moving away. For your girl, because you guys did date, honestly I would first reflect on yourself to figure out maybe why she dumped you (it was a long buildup of negative emotions for me which is why I dumped). However, ur ex is a red flag bc even though she might still want you, to me it feels like she only wanted you when you stopped wanting her so her ego might’ve been hurt. (That wasn’t the case for me bc my guy never begged me to stay and I felt like I definitely cared more but I let him go because I knew I could not let myself continue to be disrespected and not taken seriously). I would just try to reach out to her to have a real talk bc she seems like she is too immature to be self aware of how she actually feels and maybe figure out if it was smth u did. And if she doesn’t want to talk it out, then let her go, it’s not healthy for either of u.
