What should you do to keep a long distance relationship alive ?

Communication is important. Also giving each other space sometimes, it can be easy to get paranoid and clingy when they are far away, you don't want your imagination filling in the gaps.

Just keep talking with them as much as possible really. It's almost like you have to over compensate because you can't see or have physical contact with them,

There's always FB to post photos and msgs to their wall to keep them actively in your life if you want to be public about it

Include them in your everyday life as much as possible to show that they are being thought of

For that I need to enter into long distance relationship first..

show that you care and love the person.
write it etc

kiss

have a mistress.
