Kevin, if only you knew then...

The night before Britney Spears filed for divorce, PEOPLE caught up with Kevin Federline in Toronto after he cohosted an episode of Canada's Much on Demand music-video show.

You're on this huge promotional tour – and you're alone. Is it to set yourself apart as an artist or because Britney is with the kids? Of course, and the kids are too little. I don't want to bring the little one on the road, especially. There's no pictures of him out there yet or anything like that so, I really try to keep them as safe as possible.

You've said that you and Britney have a fiery relationship. What makes you guys work? She's the spice and I'm kinda like the sweet in it. I'm the laid-back person. She's always hyperactive and running around crazy and I don't know, it just works. I calm her down and she speeds me up.

So, would you say you're misunderstood? Definitely, definitely. We are, we are. I mean, that's the way it is. I don't know why it's that way, but that's what they do to us. It's all right. We don't care cause we're happy.

Does she support you? She supports me. I support her. I mean, you know, it's simple. It's one word. And that word is love. And I got a lot of love for her. Plus, you guys have a new family.That's what I mean. We're a family. It's cool. It's great.

Is it hard being away from them? Man, it is hard. It's hard. I mean, I've got a little bit of experience in it, you know, I've had to be away from my other kids, so having to do that I really know how it feels. When it gets to me I think about them and know I'll be there soon.

Because you guys are so different, do you fight? Of course. We're people, like, it's like any relationship. We have our ups and downs and we work through everything that we possibly can. If we can't work through it, we drop it and that's where it stays.

What would you say to critics who knock you guys? I'm happy. I don't care what other people say or think. I'm happy. I'm blessed. I'm proud of my life and that's it. That's all that matters.

So how does it feel to have a new baby, a new album, and more? I feel great. I feel like I'm on top of my game right now. I'm very, very involved in every aspect of my life right now and I'll make sure I keep to it.

How's your personal life? We're good. Like I said, we have our times and our spats and all that stuff, but other than that we're good. It's a lot of hard work, but we knew it was gonna be that way and we're dealing with it day to day.

With lots of communication? All the time, all the time. It's not like we fight or anything all the time. It's just, you know, it gets tiring when you're up all night with the kids and you gotta go to work the next day and me and her have to learn to find time for me and her.

Have you been doing that? We haven't been able to do it lately. I think that that's part of the problem but we'll be all right. We'll be fine. I talk to her all the time. She can't wait for me to get home.

Poor guy....am I really the only one who feels sorry for him?
