RANT ABOUT BF's MOM (sorry its long)

Im a little irritated right now idk if im over reacting but my partners mom has always been an issue granted ive gaven her many chances me and my boyfriend are 16 and have been dating a year and 4 months now and his mom is absolutely still crazy about keeping an eye on us, besides that fact about two months ago she tried to basically convince my boyfriend to get a new girlfriend because iam shy and boring "have no personality" and am "always mad at her son" when im in fact not. Now as i heard this i was upset and mad having be told he deserved better than me so i confronted her by sending her a message not any cussing just apologizing that im not good enough for the family and of course she never replied to me only my mom when my mom found out and sent her a message my parnters mom of course got scared and said that my boyfriend was lying about what she said and that it was all my boyfriends fault which obviously not. Fast forward to now She has just found a video of me and my parnter in my bed at my grandmas iam FULLY clothed as in leggings and a big sweater and hes fully clothed asleep laying on me idk how she found this on my twitter but she did and is mad i guess to the point my boyfriend is saying dont text him till its safe my mom dosnt like me and my boyfriend alone either even at the ZOO i think its ridicolous only person who lets us have alone time is my grandma i think trust is needed here or am i wrong ? Because i think none of this would be a big deal if they trusted us instead of "knowing how teenagers are" its irritating honestly...
