Your husband is in charge of himself---he can choose to stop this mess, or to keep allowing it. I find it unhealthy for your relationship if he has chosen to keep allowing this mess when you have informed it is suspicious.
Now you have the choice---you have the power. You can choose to keep putting up with HIS mess, or you can choose to stop allowing it.
I strongly encourage you to STOP allowing it by moving on from this man. I wouldn't even bother discussing it with him any further. I'd resort to ACTION rather than talk that goes in one ear and out the other to get the point across that HEY THIS ISN'T RIGHT, BABY!
That is disrespectful to you. You are worth so much more than what he is giving you. Don't settle. Your life is too precious, too short, to put up with his mess.
The power is yours. How will you use it?
ASSERT! Get what you deserve, WhyIsThisMyLife
! He'll be sorry he screwed over such a strong, assertive woman!
