i'll say it, those are sexual cues, it's quite possible she is trying to "tag" you, she possibly sees the changes you are making, getting a life, not focusing as much energy & attention on her (although I'll say it, that date with the special foods, etc. that did scream overtrying on your part, it showed you were trying hard to impress you).
But the "tagging" part is pretty evident. She mentioned before if I read correctly that you should go out & have sex with someone else. She puts that thought out there for you to go get some so she doesn't feel as guilty. But.... the thoughts sits in her mind since she originated it, she then starts to imagine you having sex with someone. If she has had a sexual encounter with another man, she knows the excitement that the "new" feelings produce (they are just feelings) but the flipside is this. She then gets an idea that you will experience the same thing, something new & exciting and then the idea of you moving on without her gets her off balance. Up until now, this has been her decision. You entered this relationship model together, you both consented to get together, be married, have kids, etc. etc. etc. She entered into a new relationship model without you, she made that decision without you, she has power now and control. She hasn't initiated a separation or divorce and truth be told, even if she talks about it, I don't think she will do it. She likes the security of having the husband at home who loves her and will always be waiting to take her back if SHE decides to come back.
Let's get back to the sex thing because it's all related. She has mentioned sex several times. If she is having sex with someone else, that in itself is very exciting, it's forbidden, it's adultery, it's bad, it's everything she shouldn't be doing and the allure is intoxicating. Here is the flipside to this, how about if she can have sex with 2 men? That other guy and you, that would be very exciting. Don't ever believe that women don't want to have sex with more than one man, even married women. Women in their 30s & early 40s go through a lot of changes hormonally, women enter their sexual prime in their 30s due to an increase in testosterone. I'm not sure when that tapers off but she may have been thinking about for sometime.
Anyways I'm long winded as usual and I'll try to bring it home, she mentions sex around you several times, the way she arches her back and pushes her chest out to accent her breasts so that you will notice, she is trying to draw you in. I won't be surprised when she "tags" you and you have sex with her, it will be exciting sex for both of you: she will do things that she hasn't done for what seems like forever and you will invariably do what it takes to impress her during this and you will give her the best sex you have ever given her, which is probably something raw & animal like and it's probably something she's been wanting for some time.
This will lead you to believe that she wants to come back and be with you (and I'm not saying that's impossible either) but if I'm correct, she will just be "tagging" you, to make you believe this so that she still has power & control over the relationship you both have.
I'll be following this thread, I'm not predicting the future, it's just I've seen & read about this and it's almost like it's starting to follow a script of sorts.
If I'm mistaken nothing happens, if I'm not though, watch for her to continue talking about sex, showing you some more attention, starting to be a little nicer than usual, throwing you all sorts of signals to throw you off balance.
I can't tell you if you should or shouldn't have sex either. But knowing some of this info does kind of put in the driver's seat a little bit.
