I had gf with whom I've spent total of 9 months of long distance relationship and met only twice . She is in another city and met a guy friend who was 5 years older than her. I couldn't meet her due to the pandemic and that 5 year older guys started picking her up from her flat to her classes and started going out for a coffee and it lasted for a month and now she told me that it isn't working between us and we have no compatibility. So I am choosing him. What should I do?
