According to an interview, she was being questioned about her opinion on gays. She mentions that her boyfriend, (not sure if he was the man you're talking about) said that he was against gays and told her that she wouldn't get anywhere with her music and her recent career. That's why she dropped him. Again, I'm not sure if this is the same guy you've mentioned.
...Although, I hope it is. Then I wouldn't have to worry about some stupid social popularity-seeker who terrorizes and accuses my poor GaGaloo's life.
Anyways, she had A TON of boyfriends before. Don't think that she'll be getting married soon, or ever, because, like Marokia said, she doesn't have time for one, and she's not exactly the type to have kids and drop her career. WE are her children, and WE are her husband/boyfriend. She's doing this for us, therefore, I treat her like family. After all, she does comment on Facebook, "...by the way, if anyone feels lonely over the break, there's always an empty seat at my family's table."
