The bigger question is "why do you care?" If he's an ex you really shouldn't be stalking him or the girl in order to find information about him. And yes, checking the girls profile to see info about him is stalking. Don't worry about what he's doing, go have fun you silly girl. :).
No clue why he's lying...
instead of wondering why.. go out and enjoy life and have fun! He's your EX for a reason!!
Maybe out of consideration for your feelings. He doesn't want to brag to you that he has moved on.
hmm...should prolly quit FB stalking her...that's a waste of time. She sounds like a bobble head...and i'm sure after awhile of viewing the squiggly shyt she's putting on there about your ex, you're probably at the vomiting stage. So...save yourself the ralphing and move on. If he wants to lie to you about something like that...than good for him...just shows how much you can't trust him, and how thankful you should be that he's your ex.
I have to agree with creamsicle too. It's good that you can check her fb cos at least you know so you're not sucked into his lies. Get yourself busy and go have a good time, that girls obviously nothing compared to you otherwise he wouldn't be trying to keep in touch.
I'm going with creamsicle's second answer....
every break up is hard, even for the one who breaks it off. I wouldn't mention if I was seeing someone as for one thing, it would no longer be their business and I really wouldnt want to hurt their feelings........
If I was a heartless cad, than I might mention it...........
maybe he's a douche queer.
Maybe he is just a jerky jerk.
Maybe she's not his girlfriend, maybe she really likes him a lot (more than he likes her)
Maybe he wants you to think he's still single because he'd still "do you" if you gave him a chance.
