Get specific with your texts and tell him exactly what you like. For example, "I love the color of your eyes" is better than "You are cute." Something like "I just adore your smile" or "I love that you are so tall!" may also keep him thinking about you longer than a more generic compliment.
If you know him well, then compliment a strong, positive personality trait. Say something about how confident, kind, or humorous he is. Compliments are a great way to make someone feel self-conscious and lead to blushing, but in a positive way.
Men like being complimented on their appearance, as well as their personality. Nicknames are a great way to express affection and familiarity. "Cutie" or Good-looking" are great nicknames when flirting, while names like "Babe" or "Honey" are better for committed relationships.
Among what men want to hear from women, positive comments about how handsome they look are one of the major compliments. If your man looks good, you should not hesitate to remind him of how handsome he looks.
According to Steve Harvey, if you provide a man with these three things in a relationship, he won't leave: support, loyalty, and intimacy. Harvey says that men may hide behind their macho demeanors, but in the end they just want to feel special.
In plain language: Men often feel most loved by the women in their lives when their partners hug them, kiss them, smile at them, and explicitly offer gratitude, praise, and words of affection. Men also feel loved and connected through sexuality, often to a greater degree than women do.
Playfully teasing him will make him blush a little from embarrassment. Just don't say anything that's too mean, or else you'll hurt his feelings. Sending flirty, playful messages is a great way to turn him on and make him blush.
Simply be courteous and keep some physical distance between you two whenever you meet. Let him have his space but do let him know you miss him once in a while. Remind him of the fun things you did together before but not anymore. Communicate instead of giving the cold shoulder, hoping to send a message.
You were the first thing I thought of when I woke up. You'll never guess what you were doing in my dream last night… Thinking about last night and can't stop grinning like an idiot. There's an empty spot next to me waiting for you to fill it.
