Libra woman confused by scorpio co-worker

I am so confused , but not confident enough to push the questions I want answered . Just ended a relationship with a scorp , when another one just waltzed into my direct workspace . At first he seemed more interested in me than me in him , I left my man and then this one started dominating my brain . We have great energy together , we can laugh and be weird at work together , so much so that co-workers have already coupled us , even though that hasn't happened .
We have both recently been through the mill as far as relationships go , plus add the pressure of having to work directly together . The path has not been always smooth , I have been upset with him in work related incidents and have blown up , him being a scorpio , he became very stubborn , we have since smoothed out our issues and communicate really well now .
We have spoken a little about our relationships , our kids , but he frequently pulls away after , giving me mixed messages . I had tried to play coy after that and ask him if he had friends to set me up with , not wanting to seem like an idiot that i had feelings for him that weren't reciprocated ....
Since then I have dropped hints about him having nice ab's , about him getting really great at communicating at work , about him giving me great advice at work , he seems to be opening up more , but i'm still confused , 2 nights ago i texted him a sweet dreams , he responded likewise immediately , last night I texted nothing and did not realize till the am that he had texted me , he texted me a pic he took of our cars parked together with me in the pic ( I didn't even know he had taken it) , today we spoke about our kids first day of school and he texted me a pic of his little one on her first day ( i love his daughter , we get along like we've known each other forever) , so I did the same . He seems to be opening up more , but this Libra is getting inpatient , I go to sleep thinking about him , have dreamt about him and wake up thinking about him , he has all my nerve endings in a jumble and I just want to know how he feels , but I don't want to scare him away
advice please

Ok , but from what I wrote , what do you think , especially you being a Scorpio male

I am pretty direct actually , just in this case do not want to feel like an idiot at work , because we do work directly together it's a risk .I will probably get up the nerve sooner rather than later because he takes my breath away and I gotta know .
Thanks for your advice , it will be well taken

Well I sent him an email telling him I was interested in him , his mind , humour and ab's , that I would like to get to know each other slowly , that we keep stuff professional at work , etc in a nutshell .....I also asked he be honest with me In return and that I was a big enough girl to handle rejection if he did not feel the same ....
All I got was a winky face in return .....
I feel like an asshole , pretty embarrassed .....
