When you accompany her to exercise, you need to be tough and practice some difficult projects, so that your wife will think you are a serious man and don't dress too cool. You can take this opportunity to observe your wife's micro-expression, which will betray everything. If her eyes are clear, it proves that her heart is still there, but if she frowns and her eyes move, you should be careful.
Of course, she may just want you to have face and a woman's heart and look for a needle in a haystack. You don't know what women are thinking. What you need to do is not to think blindly. If you really think so, you can't startle them, or your temporary lack of calm may lead to cracks in the relationship between mixed cigarettes. You need proof. Without proof, it's useless to think about anything.
Finally, I recommend several good ways to lock a woman's heart. You can find a few of her girlfriends to go to the gym, and one more person will give you an extra safety factor. In addition, you can often take her out to travel. After a long time, you may find that you should go out more when you come back, so that you will forget to go to the gym. Women are curious, and they will soon forget something. You can use this to make her forget the gym.
