He seems like he likes you, but if his phone is broken; you are the last to know. He always invites them over around 12-4 in the morning to hangout cause he is bored, but never has asks you to hang out. He came to your home to visit your family (in another city) and seemed to have a good time. When you say you want to talk about something serious not even to do with love he grunts. What is he thinking about?
He is lacking something in life, either family, friends or something more that he can't figure out and no one can point it out for him. When he visits your family in another city he wants to getaway from his own life. He is too much into himself that he cares less for the people around him. If you are in a relationship with this man, it won't last much longer. Believe me or not but I probably understand this kind of man better than you do.
