You feel as if you're on shaky ground: a little self-conscious and a lot overwhelmed. Something's not right in your romantic relationship. They've pulled away; they're uncommunicative -- even downright nasty. Are they cheating? Maybe, maybe not. Before you broach the subject, make sure it's not a figment of your imagination. Breathe, talk to someone, observe. Don't fly off the handle just yet. Give them time to shape up.
