I’m convinced when you rekindle a relationship with someone (friend, family, ex, etc), something will always resurface to show you why you should have left it burned and dried up.
If they don't involve you, step back.
If they don't tell you, don't ask.
If they don't invite you, don't go.
If they don't value you, don't stay.
Know your place in people's lives.
It's not ego. It's self-respect.
