Ghosted her since few days ago. Relationship was on and off for nearly 2 years but I can't go back again. Feeling lost and quite bored to be honest. Keep having to stop myself from reaching out. Not sure how to get out of this slump as such a big portion of my life was with her given our ages and I feel like shit even though I don't really want her back given how she treated me, flirting and kissing another guy. Any advice would be appreciated.
