I talked to my ex after almost a year. I realized I still miss her and might want to be with her again.
How did you feel when you talked to her?
I felt a warm sensation in my chest. I started to have feelings for her again.
It's okay to acknowledge that you're having these feelings since she was an important part of your life before. However, it's important to be able to let go of previous relationships and move on to new ones.
I plan to contact her as soon as possible and ask her if we can start dating again.
Before you do that, think about why you broke up and whether or not that issue would be fixed after getting back together.   If you both feel that things might be different, that maybe give it a try and take it slow.
