Self help books, suggest titles please.

I'm still with friends after the game. Hanging out, a few beers, just BSing, fun.
I have a busy work week so that'll tie me up a bit. I do have after work plans for a few days. If nothing else a nice drive seems to help clear the mind.

I know I have posted quite a bit about W texts. I do it for advice on replies. I feel the communication is good and I do like to hear from her. I try to be supportive since lately it's been about her mom, W stress, worries. I don't want to be needy, clingy, or too excited or express too many emotions. I'm not sure why she is confiding on me and telling me things. I get confused but try to stay focused. Difficult.

I have not talked to MIL. I have no real knowledge of what her and W talked about. If MIL wants to call me about it I will hear her out.

I'm not sure 180 or "as if" attitude will hit her too much. I'm not sure. I know they help me. But it seems like I don't care or I'm not trying for her anymore. A few told me to pursue some, she wants it. Others asked if I'm still reading and working on me. She needs a reality check and time. I need time to continue my work on me. I'm afraid of we spend too much more time away from each other the worse it will be. Same for the length of the affair.
