Here's the Red Flags answer to a common question...

"I  feel like I've lost my friend to a relationship. S/he's changed so much, doesn't want to hear what I have to say about the relationship, and never accepts invitations anymore. Why should I keep trying?

It hurts to feel rejected by a friend and to see them being hurt by a dating partner. Know that if they're not ready to see what's going on, it can be hard to hear your opinions about it. And their partner may keep them from accepting your invitations. Be patient and continue to include your friend in your life even if s/he turns down your invitations. Just calling to say hope youre doing well or sending a funny joke or lunch invitation over e-mail will let your friend you still care.

Your friend needs you now more than ever, and it takes a while to leave any large part of your life behind be it a job, home or relationship. If your friend considers moving on from the relationship but looks around and feels like everyone's disappeared, s/he may stay in the situation, thinking their partner is the only person left to be with. During breakup time, someone whos been around for the long haul can provide some much-needed perspective.
