There is a woman I see at the gym everyday. I used to give her eye contact and a smile all the time as I used to think about asking her out. I guess I was being flirty in a way. She seemed responsive to it and it appeared she may have liked it at first. Over time I found out she is married and has a child. It was also obvious some months ago she was pregnant. I've stopped trying to "be flirty" with her because of it over the last couple months. Yet recently last week she seemed to always be looking at me in the distance in a cute way. If I walked by her she would avoid eye contact with me and look away but with a smile on her face. Now this week. She seems mad at me when I walk by her and won't look at me and even puts her head down to avoid looking at me and with an upset or negative/neutral look on her face. Just out of no where this week. Why would a married woman with children act like this suddenly after like a year of this and suddenly she acts like this? I don't even feel like I've done anything wrong. I'm okay with her not wanting a relationship with me obviously, but why does she seem like she has to hate me now?
