One time napag usapan namin ng mother in law ko regarding owning a place,pinagsabihan nya ako na bumili na daw kami ng lot or if not house and lot , bakit until now nag rerent padin kami she said ano ba daw ang plan namin? I was off that time , napatigil nalang ako at wala akong nasagot . Is it okay na mangiaalam sya on our decisions ?

For me, it's just her way of checking into your current status. Reality check, kumbaga, and if it's constructively stated then I think I won't get offended (if I were in your shoes). Siguro gusto lang nila itanong kung ano ang mga prospects niyo at hindi naman siguro pangingialam na. Wag mo nalang masyadong damdamin if they ask questions like this. I'm sure they just want the best for us. And it would help if your spouse take into matters like this—yung pakikipagusap sa parents niya.
