Ok so me and my ex were together for about 5 months. We were very closed and we would talk to each other every night. Last week i found out that she was cheating on me for about 2 weeks. The only reason I spotted this was she was being too distante. Now I have to see her at the homecoming dance with another guy. I don't know how I should react to this. I still have that irrational thought that we might get back together or there is still a chance. Any tips for getting over my ex?
