Questions: Relationships

My friend's spouse and she have been married for about 12 years. There was this girl he wanted to date, but she moved away. She has returned from Illinois to Memphis. Her mother appears to be causing a problem by adding her husband on Facebook. Her mother disrespects his wife by calling her daughter and informing her about the man. Now that she has returned after all these years, she is attempting to spice things up. This girl cheats in every relationship. She has a child but didn’t bother to tell the guy he wasn’t the father until teenage years.

I’m curious about what other couples do. I try to get into the habit of saying good morning and good night every day with my boyfriend to remind him that I’m thinking about him from the time I wake up to the time I go to bed. I find that if he doesn’t say it, I feel like I miss him painfully but if he does say it, I still miss him but I feel a sense of comfort. And if I don’t say it, I feel like my day hasn’t started/ended fully. Let me know your thoughts!
