I need a breakup spell

You need to take a deep breath and tell them. Yes, it will be tough, yes it will hurt, but it is better than living a lie. Staying in an unhappy relationship will harm both of you in the long term. Look for a self-confidence chant to help you find the strength to have the situation.

As for the actual breakup talk, if you're scared for your safety, I would call them. I'm assuming you're in quarantine like the rest of the world, so call them [do not text them. In-person is best, but for your safety, call them] You'll both have time to heal and get over the breakup in solitude [and if they show up at your door, call the cops. The person cannot be at your house if they don't live there at this time]

Thanks, people who replied, for advice. I will follow this advice to the best of my ability.
