If you're in love, you probably think about your man a hundred times a day, so why not let him know that? Tiny little things make a difference; his favorite meal or takeaway in the middle of a busy week. A little gift - even something as simple as getting him a new pair of shoes when you've noticed that his are wearing out!
Thoughtful acts remind him that he's loved, and when he gets this sort of attention when he doesn't ask for it, he's never going to go anywhere else. So, give him a massage when he looks stressed, and don't wait for him to ask. Send him a sexy text to read when he's on his lunch break at work - gently let him know he's on your mind. Best of all? He'll give you the attention right back.
