Straight woman playing games

I have been at my job now about 7 year well a year ago this lady was hired in my dept. immediately by the way I look she knew I was gay. She really never talked to me or said hi or anything. About 3 months ago all that changed now when I would walk by her she would look up and say in a seductive playful tone watcha doing where ya going I never engaged in it just thought she was just being really nice but was strange all of a sudden she is kinda talking to me. One day I was in the copier room and she walked in and behind my back she like grabbed by bicep and squeezed it and walked out the room before I could turn around now that was really strange she had never talked to me much, let alone touch me like that . So the next day I started talking to her gave her long stares and kinda just let her know thru my eyes I am into her too. I noticed she would only talk to me when I was walking by and she would start the conversations with me and I would talk with her a little and walk on. Well I fell head over heels for this lady I thought she liked me even though she really never said that but her actions would say another thing. I started to get distracted at work thinking g about her and it never seemed like neither one of us was going to make a move and say hey let’s hang out. So I decided to just stop this game and just ignore her don’t walk by her get her out my head the dept she works in is moving out of my dept so we were not going to see each other again anyways then the strangest thing happen she saw me by the. Bathroom and asked me if I would become her personal trainer that she was thinking about getting fit and she see I am in Good shape and wanted to hire me. I told her yes this was so strange since in 1 week we would not even be seeing each other again. Now I am going to train her on the weekends I agreed to it l. All this leads me to believe she likes me right so as I was asking her for directions to her house so we could train together she all of a sudden mentions her husband and gets a little nervous so I said well we can work out at a gym she agrees to a gym now not her home since she has a husband this whole time never mentioned a husband until I was going to come over and train her. So I agreed to a gym setting and we are meeting next week but I am head over heels crazy for her and she has to know this I stutter when we talk I forget things when she’s around it’s so obvious to everyone who looks at me when I am around her. So yesterday she comes in my office and talks about the exercises we will be doing I seductively looked her up and down she gave me like the cold shoulder and when she started talking to me she looked away as I was starring at her with a stern look like not interested so I am wondering what does she really want personal training lesson really or just to make me crazy cause she likes the attention or the way I googley eye her when she talks to me it’s so weird. I have decided to never look at her like that again but the weirdest thing happen after that incident the other day she comes back in my office talks again about training and I kept it professional and then she like licked her tongue out like being quirky and looked back at me with a huge smile now I am right back going crazy again over her. Do you think she is playing games everything within me tells me she is playing games cause she is married and maybe likes the attention she is also older than me I am so confused. I really like her I am crushing on her so much but why would she all of a sudden want personal training lessons but this whole year she has never once talked about working out or even lifting weight I here her conversations with other coworker and never has it been about anything health or fit or working out or trying to get back into the gym. She is not overweight or anything. Just weird that her dept is now moving and she wants personal training lessons weird
