How to know for sure that your husband loves you and isn't just using you to benefit from what you do for him daily? (from food, to cleaning, to sex, to boost his motivation, you get the idea
You must watch the expression on his face when you two meet up at the end of the work day. Is he like really happy to see you or does he just ask you questions about what you did and if this is done, and that is done, etc. Husbands who love their wives are really happy to see them after several hours of not seeing them. They also like to talk to their wives, touch them, hug them, kiss them and do things for them. They want her to be happy and will not interfere too much in her decisions about the home. They will also go out of their way to get her whatever she wants.
So all that.
