Can't figure him out!

[jsav]

Hi, I'm new here, I was reading some posts and
thought maybe I could finally get some answers
here!!
My boss, who is around my age AND attached
seems to be flirting with me all the time. I am
also attached and he is aware of that.
He frequently makes eye contact and will tell
me I look good and dress nice, etc. I am
flattered by his comments but I get so
embarrassed when he starts doing this. The other
day I was talking about my bf and he said something
like.. So isnt he enough man for you? I got beet
red and I don't even remember what I said.
Today I walked into his office and he asked me
what I was wearing because I smelled so nice.
Then, there are days that he acts very professional
and "bosslike" and none of this happens. He is
a very good looking guy and seems to know it.
I just don't know how to handle it! I don't know
if he's trying to lead into something or if he is
just flirting for the fun of it. I am NOT a natural
flirt and I get embarrassed by this so easily. If
I knew this was just fun for him then I probably
wouldnt care and could act more natural.
Maybe I'm naive but Im also so surprised he would
be trying for anything since he is attached.
I have to admit I don't mind the attention but
then I'm wondering if he thinks I'm attracted to
him and that's why he is doing this.
Any opinions on this? Do some attached men
do this just to be flirty and not mean anything
by it or is he.. uh.. trying to get in my pants??
I get so nervous around him and I just want to
act normal!
Thanks!
