Nurturing yourself while you're in a relationship decreases the impact breaking up has if and when it happens. The more you keep the connection with yourself and don't lose a part of you in the relationship, the healthier you stay. You lose your identity in a relationship when you don't nurture yourself. When family doesn't honor you and see your worth, sometimes you just have to distance yourself from them so that you reconnect with the brilliant, worthy you. Not everyone is capable of seeing what you are, so it's important to continue nurturing and supporting yourself as if you were your own child or best friend.  When your partner has a friend who is also an ex, how do you feel about that? Do they talk all the time? Do they have to communicate because of shared custody of children? Do they communicate more than you'd like? It's important to understand where your line is and when your partner is crossing it, otherwise, their ex becomes a part of your relationship, which can be damaging if you're not all good friends to begin with.
