I agree with the others about the no contact rule. But I wanted to add you cannot stay so hung up on your ex. I'm sure you had a lovely relationship but now it's time to focus on you. Go find some things you enjoy doing, get some new or expand on old hobbies. You must start bettering yourself and taking care of yourself for the grieving time to work faster, because if you sit around doing nothing ( i'm not saying you are this is just an example) all day everyday for a month or more then of course it is going to be harder. Make sure to put yourself first lovely. I'm sorry that you and your ex partner separated but stay strong and keep your head up, you'll be okay <3
