Do what it takes to start a party and flirt with anyone who strikes your fancy. After all, you are feeling way more social than usual, so get out there and make some new friends!
Instead of waiting for someone else to make plans, take the lead and organize them yourself. Think of what you’d like to do most with your loved one, then take steps to make it happen.
If you’re second-guessing a situation you’ve gotten yourself into, good. It’s about time your conscience kicked in. This person isn’t what they’re cracked up to be; the sooner you accept that and move on, the better.
