I am in an awkward situation. My partner of 5 years made a friend at work and wanted us to meet because I am pretty much an introvert with little to no friends and my partner was certain her co-worker/friend and I would make good friends.

After the three of us all went out for some drinks a handful of times we all were becoming very good friends and having a great time. The co-worker and I even began to talk through facebook messaging a couple times pretty in depth and it seemed like we were pretty cool with each other. Always goofing around and having a laugh. It was nice I figured this was what a friend is supposed to be like.

Since I am very new at this whole making friends thing and I am not super good at it, either, I thought I was noticing some weird behaviors from the co-worker. It seemed to me like she was pretty needy of my attention one night in particular and was rather flirtatious with me as well.

While all three of us were out at a bar, we had run into a couple that my partner and I hang out with and they had even pointed out to me the oddly flirtatious behavior that was taking place.

The next day I decided to ask the co-worker if she was catching feelings for me and I also wanted to make it clear to her that I was only interested in being friends and that I liked it the way it was just friends.

Now things are very awkward and the co-worker has gone from talking to me daily as a friend to zero communication and when I try to talk to my partner about it she gets frustrated and mad at me.

Was I in the wrong here? Why would this co-worker stop talking to me just because I laid out where I stand in terms of feelings? I do not understand how to have friends at all and this is really confusing and awkward for me.

I really appreciate your help.
