Did she love me?
At the time probably yes, now we don’t know/probably not. Note that love is complicated and has different types like there is passionate love and companionate love. Passionate love rises quickly within 6 months to 1.5 years, it reaches its peak. Then it goes down hill and within 7 years it goes to its lowest point. This happens to everybody not just you, naturally this love converts into companionate love over this time and when that does not happen it needs to end. Companionate love is slow in rising but it is also more lasting. Two main components of companionate love are 1) emotional intimacy - ability to share anything 2) commitment - that feeling that it is YOUR responsibility to help them if they need something. Any action that violates these will result in losing love.
Some actions that hurt love: lying, hiding things, feeling you’re the only one who cares etc.
Know this, true love or companionate love is something both people nurture and grow, you cannot do it all on your own. If it ended then something went wrong, maybe nobody was at fault.
Take your time and heal my friend.
