Answer:
You're gonna cry or miss their presence,and that's perfectly fine. But do not I repeat DO NOT go back. Things happen for a reason, their gonna give you some sad story and expect you to give in and take them back but do the exact opposite. You're better off without them because you didn't need them anyway. Do stuff that cheers you up so you don't think abt that person or STAY BUSY. Block them on everything, and now that you have more time to yourself focus on yourself and do things that make YOU happy. Be around family and friends that will support you. Achieve something you always wanted to achieve. And once you're doing better and they see that you're happy their gonna regret losing you.
