Is it advisable for married couples to sleep in separate bedrooms?

'Dear Pulse,

My name is Patricia and I have been married for 5 years now to my first love. Our is currently facing a turmoil over my husband's changed attitude and insistence on sleeping in the guest bedroom.

This strange behaviour began when he cam back from a 6 months course in the UK. Our sex life is practically non-existent as I practically have to beg him for sex.

I suspect he must have found a lover in England, especially with the way he has become secretive. One night, I walked into the guest room at about 2am and saw him on his laptop chatting.

When I tried to see what he was doing, he hurriedly closed the computer.

I am really fed up and don't know what to do.

I want your readers to help me out here.

Pat.'
