I'm surprised you underestimated their relationship in that way. They've been together for ages (and Fed doesn't seem like the type of guy who'd lead a girl on if he didn't like her), are practically inseperable and are as good as married.
As for his career...
Well, something needs to change the way it's been going this past year. If he can't get a coach, then maybe this'll be the thing that'll bring him a positive change of attitude.
Well, I'll explain.
After years of watching high-profile tennis players, I've just noticed they seem to have a change of girlfriends now and again. Some relationships are more lasting than others, but it's just rare that they stick with.. the first girl, showing up at tennis matches.
He might have dated somebody before her, but Mirka seems to be the first actually touring with him? How long have they been dating? He's only 27, and it just seems he's been dating her for a long time. I would just think he might have dated some other women, not that he's a "dawg" or anything. Even Pete had a few girlfriends before he settled down.
It's none of my business, so obviously I'm just speculating, and I really shouldn't be. I just hope everything is OK with Roger--and I'm not just talking about his tennis. It's obvious he's happy about the baby, but then again, well I still think there is something really strange going-on. It's just this feeling I have.
I hope I'm wrong because I really admire Roger, and I'm sure Mirka is a good person. But even good people get caught in bad relationships.. or bad situations. I hope I'm wrong.
