Since Cory said some of what I wanted to say, I will simply state my agreement!
Overall I think my comments would really depend on what you're trying to do with this. That was my first question! Are you doing a short story--and is it just for fun, or is it meant to be sent out to magazines/etc.? (Or if you don't know yet, and just want to write to write. Which I love to do. I have so much of that stuff on my hard drive it's criminal...)
It's good, but in the early part, it tends a little bit towards the overdramatic here and there - but that might be what you intended! Most of that stems from some of the stylistic things Cory suggested--but yeah, that might be why you included them, so it's hard to say.
I'd name Dan sooner to prevent confusion, and/or specify that Lexy is his wife's name fairly early on. Yeah, I caught on eventually, but it made me stutter for a second.
