I don't even know please help

Kailea

So my ex broke up with me because we didn't talk or see each other much and he said he still loved me but now he won't text me back and yup know on messenger how you can see if the person saw your text he saw it but didn't reply and I know everything isn't about me but I have texted him and he hasn't replied in days and we have been friends for a long time before we started dating and I don't want that ruined. I just need help
