What do you think she wants from me? Read below?

I am a 33 years old, single man, who works as a teaching assistant. I’ve known Ms. V for 2 years since I first became her teaching assistant. Ms. V is married and has three kids. Although she is 7 years older than me, I find her quite attractive when I first saw her. When I first know Ms. V, I know she is a religious person, her family is a religious family, her husband works at a church. I respect her, never make a move on her, and never hint her that I am attracted to her. As time goes by, she opens herself up to me, discussing her marriage issues, her struggles, and her disappointments in her husband. Over the 2 years that we know each other, I have developed feeling for her. When we went out of town for training together, she admitted she also has feeling for me. During our training, we ended up having sex. Afterward, she avoided me for a month and I thought maybe it was just a fling. But after one month, she shows up at my house unannounced and she had sex again. Sometime she avoided me and I thought maybe she changed her mind, but then again she shows for sex and then avoid me again. It is like sex, avoid moment, sex, avoid moment, sex…. is she only interested in having sex or she needs time to figure things out?
