"Running buddy" problems? Contrast in ability?

Recently one of my friends agreed to start running with me regularly. But I think I might be trying to take on too much because he is a much more advanced runner than me even though I haven't been running since December and he hasn't been running since last summer. But he works out and I haven't been doing any cross training so I'm more out of shape than him. I have terrible stamina (better than most, but in the running world, sucky.) And he's like a metronome! I keep getting embarred by how slow and poorly trained I am, should I find another running buddy on my level? Or do you think it won't matter to him bc I'm a girl? lol
