Struggling to Let Go of Someone Who Talks to My Exes

I’m so sorry for what you're going through. It sounds like you are very tough. If your grandmother's house is going to be a safe environment for you, it may be best if you focus all of your energy on moving there. Navigating relationships is challenging for everyone, but we can make better, stronger decisions when we're under less stress. Hopefully once you're in a better home environment you will have a clear perspective to find a partner that doesn't add stress to your life. It's hard letting go, but it's easier to let go when you know something's holding you down.
