My boyfriend is 37 years old. He has a really close relationship w his dad fine, but their is a thing as to close. I pay all the bill's and some of his. I have my own house and we have been together for 3 years. His dad calls every 2 hour's when he's here. Makes sure he's not out of town. Makes him stay with him instead of staying with me. Does anything he can do to get his son down at his house. Let's his dad run his life. Then if we go out of town his dad comes with because he doesn't get out enough. Hello his dad has been married twice and they didn't work so what he doesn't want his son to be happy. My boyfriend says all the time that he is going to marry me someday but he has to spend as much time with his dad cause he's two other brother's don't listen to his dad so he has to because it makes his dad happy. What about what makes me happy do I matter? Help give me the answer's to get dear old dad out of his life so much and my boyfriend to see that he's to old to be a daddy's boy and start acting his age and stop making promise that he breaks left and right..Like I promise I will move in next week or I'll be w you tomorrow night HELP
