The main move is obviously to turn down the love and spend some time apart, but you need to plan this out correctly, or it could backfire!
How to make your boyfriend miss you in 5 easy steps
Step 1: Leave your mark
Before you even tell him you're going away for a few days/weeks/however long... you need to make sure your 'signature' is well and truly imprinted on his life.
Obviously don't start acting weird and doing things you wouldn't normally do, just make sure there are reminders of you everywhere.
Mark your scent by spraying your perfume on the pillows for example, or leave your favorite sweater somewhere he's likely to find it.
Step 2: Build up your leaving date
Seem excited about spending time away, but don't go on and on about it... leave some 'mystery' as to where you are going or what you'll be getting up to.
Steps 3: How to communicate when you are away
Calling him all the time will make you look desperate (or at least make it seem like you never left), and cutting all communication may start to make him worry. Instead, go for the occasional text message showing that you are SUPER busy, but are still thinking of him.
Step 4: A little help from your friends to make him jealous
Do you have friends in common? Are they on Facebook (or whatever social network you use)?
Before you leave, you need to make sure you have plenty of pictures of your friends and their partners kissing.
When you're apart, start uploading and tagging those photos. His newsfeed will start to look like this and his heart will start aching just a little bit.
Step 5: Make plans for your return
Before you head back home to his arms, make sure to call and arrange to do something special. It could be anything from going out for pizza through to spending a weekend alone together, but he'll be left counting the seconds till you're back, trust me!
Bonus: leave a copy of 500 Days of Summer lying around for him to watch.
