Most Helpful Girl
I hate to say this, but it takes time! The more he reaches out to you, the more you'll keep getting back! You're the only one that can control the roller coaster ride with this. You need to find ways to get over him and the relationship, because clearly it's not a healthy relationship and it makes you unhappy! We all deserve happiness, whether alone or with someone who truly appreciates and makes us happy! Take whatever time necessary to cope and accept the loss and move on, for your own peace of mind.
Try friends, dating, going out, running, hobbies, etc . Only you know when and how to put an end to your roller coaster.
