Is Nando in Love?

As I was sitting in the lounge, tonight, eating dinner, Nando received a call on his mobile. It was the woman he's been seeing. Dare I say "his girlfriend?" So, of course, I listened to his side of the conversation. He was laying on the couch next to the one I was on, so it was almost impossible not to overhear. As I took fork fulls of beef and rice, I figured out that he was giving her directions to our house. He gave very detailed directions, mentioning almost every rock and tree between our street and the main road into town. Then it happened! Just before he hung up, he said, "love you." What????
That's something I'd never heard Nando say to a woman, before. I just had to say something about it, right? "So, it's 'love you,' now, is it?"
Nando grinned sheepishly. He excused it away as something he was saying in response to her saying it. So, was he just telling me that because he was embarrassed, or does he really not love this woman and is just telling her what she wants to hear? If he is just faking it, I feel bad for her. On the other hand, what if they get so serious that he moves in with her? What happens to me, then? I went through so much trouble to get Nando a place in this house. If he leaves, maybe I'll move to London. He seems so nonchalant about her, it's hard to imagine it's that serious.
To change the uncomfortable subject, I commented on what detailed instructions she seemed to require. Like many women, she's not strong in a directional sense. My evil ex-wife, the Black Queen, who was a sailor and a great helms woman, couldn't navigate her way out of a paper bag. Nando laughed at how unsure his girlfriend was over the directions. She would be driving over tomorrow. It will be her first time coming to our house. Sadly, I won't be here to meet her, as I will be in Withernsea for my weekly radio show.
