A little context on my in laws are in my history, but I can certainly provide more information if needed to help find a solution to this current issue. My husband, son (3) and I have been very limited contact to no contact with my in laws for nearly 2 years at this point due to their atrocious behavior from the day I came into their sons life and even more so since our son was born. They have made it clear that if they can't control our lives (mainly access to our son) that they will make our lives miserable, so we have been essentially cornered into no contact with them. Roughly 2 months ago we made plans to attend an event and the days before my MIL decided to attend as well, GMIL made us aware of this and BIL played middle man and simply warned MIL we did not wish to engage with her and she needed to respect that, which she did. Last night my sister graduated and my in laws attended the ceremony as well for a family friend of theirs. We had no idea they would be there. After the event we went to my sister for pictures, at which time we noticed MIL and FIL hanging around near them and watching. We avoided them and walked to my sister and family. At this time I noticed my FIL standing behind us taking pictures of us and my MIL was literally circling us from a distance (assumingly to corner us once we left my family). My husband became very uncomfortable only noticing his mom and asked to leave after just a few minutes of congratulating my sister. As we were leaving my MIL managed to find her way next to us and simply got in a hi to my husband before we got out of there. While minor, this incident has left us both uneasy. We moved away from this city to get away from them and they still manage to make the visits back home uncomfortable. This was next level. We were being watched the entire time and it was clear. The photos from afar while I was talking with my sis, the circling, it was all too much and now we're lost on where to move forward. So, an outsiders perspective may be beneficial here. Do we stop NC to notify them this isn't ok and is making the situation worse? Do we just hope it doesn't happen again (it will, MIL is notorious for this situations). We have expressed to them that literally all we need from them is a sincere apology acknowledging their wrongdoings (hoping once they admit what they did was wrong they won't do it again) and a change of actions moving forward. They refuse this and have instead resorted to sob stories and now apparently stalking. We're rattled. Help PLEASE!
