If nothing else you need to get your financial situation on a firm legal footing while you think the problem through.
If your husband would do this to you, he is just as likely to upsticks with all the family money and savings to move to China and spend it all on his floozy, leaving you in poverty and possibly homeless
Do not say to yourself, which I rather get the feeling you are at the moment, that he may have found himself a floozy, but he wouldn't walk off with all the money/leave me permanently for her/it will all blow over he loves his family too much.
A short time ago you would have said he would never in a lifetime go off with some floozy - but he has, so at least protect yourself financially and do not keep putting it off in hope that you will wake one morning and find it was an awful dream. It isn't and the sooner you grit your teeth and face up to it the better.
