I'm still not over my ex. I cried again. Even though it's been six or seven months I feel like I should have moved on already what is my problem? Ugh

It's hard work. There is no problem - you loved and when we lose someone we love it is a death of a kind and don't be too hard on yourself. Grieve as long as you need. I'm 4 moths down the track of a breakup and my heart is still bleeding. The only thing that is going to heal us is time.
