Single and speaking to men again

Gemma

So my one and only relationship lasted 10 years and now I'm single again. It's been about 7 months although feels like years because of how bad the relationship was... anyway... a new person started at my work a couple of weeks ago and we pretty much hit it off straight away. We speak all day and even emailed back and forth all day too. When ever we see each other, there is alot if banter and flirtyness. We speak about everything and anything as well. He actually put the effort into talking to me, asking about me, my life and the quirks and little bits too... I enjoy speaking with him and feels like he wants to get to know me for me and not just get in my pants ect. Anyway, he emailed me his work number to message instead of emailing. At the same time, unaware he sent me this email, I actually went up to him to ask if he wanted my number instead. Yano thinking we talk alot and it would be nice to keep it up outside of work too.. I think i caught him off guard (and myself as I've never been for forward in my life).. anyway I got back to my computer, saved his number and sent him a message saying hi, it was me.

I got a message back saying, " he wanted to be honest with me, he's got a girlfriend"! What?! I am soooo confused! Why would you invest that much time chatting and getting to know someone of the opposite sex if you already have a girlfriend. Honestly I'm just really baffled. He then said that he hopes it hasn't caused asn awkwardness between us and it doesn't change anything his end on how we've been speaking to each other.. but he didn't want to lead me on. Then proceeded to tell me he thinks we hit it off from the moment we started speaking and if he wasn't already in a relationship, then he would deffo like to know me more.

Honestly u feel super embarrassed for readying it all wrong. I know I'm not experienced in dealing with all the dating and speaking ect, but I honestly did feel like there was something between us. Even another Co worker said she could feel something between us (no one knew we were speaking ).

I would really love / appreciate some advise or I don't... anything. I'm just really confused tbh xx
