What to do when I’ve ivertexted and he’s stopped responding?

If you feel like you over texted and the person stopped responding that most likely means that the person needs space. Time can only heal things in this case when he doesn’t want to fix things. Just give them some space and then check up on them once in a while, like once every 3-6 days so they still know you care but won’t feel annoyed by the pressure of you texting them. If that doesn’t work then try moving on. I know it’s hard but if things aren’t working out, then they’ll never work out and you both have to go separate ways
