What should I do if I love my ex
What makes you love your ex still?
Because we dont get to meet anymore and we promise we'd be together forever.
It's understandable that you still have love for your ex. If this is a relationship that you cherish, you should aim to maintain the connection as much as possible.
Once a love is gone, it's hard to get it back and I think she has changed a lot.
You should start moving on if you feel like the relationship with your ex is really over. Once you start dating you will probably find someone who you can share that love with again. Wouldn't it be nice to have a healthy loving relationship again?
