I have 2 dauhters, they are 3 years apart and are very close. We all 3 are close, but I know there is a lot they talk about with each other that they dont' feel comfortable talking to me about. They are adults. It makes me feel great knowing they have each other.
My DH has a son that is an adult also, only child, and no friends. It drives me crazy, I mean like bat shit crazy, that he calls DH 3-6 times a day for anything, everything and nothing. Oh and add at least 50 texts a day and night! Every work break, lunch break, he calls his father. And DH answers no matter what we are doing, because he feels bad. He never says "I'm busy", or "its a bad time". Even when sometimes, it really has been. Lately when I'm in the middle of a conversation and the phone rings, I stop talking, walk away, and I refuse to continue the conversation when he is done talking to him. I know its childish but it pisses me off.
My girls have tried to be close to my SS, but he just crawls further up DH 's butt.
