Hey guys, I'm '33M' and my coworker is '29F' and married. A couple of weeks back in the office we became really close friends. She was always coming to me to have a chat or we would play pool together at the Office break room. She added me in messenger and we texted back and forth. I shared a couple of songs with her and she loved it. I could sense that she was interested in me because we would flirt a few times.

A few days before our Company retreat she was showing me her pics from a few years back and I told her she looked hot and flirted a bit by saying that if I ask her old self out for a drink would she say yes and she said yes and also added that the current one would say yes as well. Then she started saying that she is having physical problems in her marriage basically the husband is not able to satisfy her in

bed and they are in the talks of having an open marriage. So I then got home and texted her that I would like to buy her a drink at our company retreat event and she said yes and I said it's a date then.

Then she started acting kinda distant and in the company retreat event she was very distant with me and anytime I wanted to talk to her she seemed not interested. Also there was this another guy in her close circle that she was spending a lot of time with and they also went to the same school. I also kinda got the vibe that they were sleeping together (touching each other and smiling at one another)

Anyway, long story short I am okay with her not feeling the same way that I felt about her and also her sleeping with another person. It's her life she can do whatever she wants. What I'm not okay is with this weird awkwardness that has developed. How do I navigate this? Do I avoid any type of interaction with her at work? If I do approach her at work and she ignores me do I ask her what's wrong? I'm really confused on what to do and I hate this awkwardness. Is there any way to go back to how things were before?
