I just noticed today that H has been taking more cash withdrawals than usual for the last two months. Just a few days ago he voluntarily told me that he's planning to sublet his colleague's apartment when his colleague moves away in a month. Supposedly that's where he's been staying for the past 2 months and he said he's paying his rent right now because he's been nice enough to let H stay there. anyways, at currently level his spending is not going to hurt our finances too much, but I wonder how I should bring it up to him, or whether I should say anything at all?? We are not legally separated so everything is still tied together.
