Used to call often in a week (just after marriage) but it backfired many times. After a few months into marriage when he finds me sad or unhappy he used to get worried and ask whether i spoke to his mom...ha ha. Now, after 6 long yrs and lots of troubles with MIL we call each other once in 2 weeks or weekly(not fixed) whereas my husband never calls his own family. I prefer quality to quantity. It is better to call and talk nicely than calling daily and giving them updates. I have tried that and it has backfired. I like the current setup better. If you call them often, I used to reveal lots of things and then get unwanted comments and then feel bad.
