Mother in law - Rant

So, I have been having some issues with my mother in law lately, and feel like I constantly have to defend myself & my parenting choices to her. My hubby works out of town for 20 days, we just had our third baby & we are in a new house… there are a lot of things I am adjusting too lately. I sent her this message today - because I feel like things have been strained between us - and she doesn’t seem overly interested in connecting lately. I know there isn’t a lot of background in this little blurb - but am I reading too much into her response - or did I somehow burn a bridge without meaning too.
