Not understanding what you mean by sexually based geared towards her.

However, some men are sexually selfish and the woman doesn't really get satisfied. So, it might be (again just a possible) that your wife is trying to enjoy sex differently and even seeing if she can trust you to be adventurous sexually. It could also be that your wife is trying to gain on her sense of self worth and she will be doing things that you may consider "strange/different". Also, she may have done her own research into why men cheat and they typically cheat for sexual reasons where women tend to cheat for companionship reasons.

As far as gaining on a more committed marriage? I think you will have to be patient with that as she has only just recently started to be intimate with you again.
