Please excuse the apparent hot headedness of this post, but something happened yesterday, and I did nothing, but I’ve been thinking and thinking about it and now Im really angry. So my SIL has become increasingly hostile towards me due to a fall-out she has had with her brother. Yes cross words were said on both parts (my husband and hers) but DH and I have since decided to distance ourselves from her. She lives with our in-laws so inevitably we will see her. Yesterday me and my 3 yo DD were sitting having a chat with in laws, in a seat that has a door opening next to it. SIL took one look at me and DD, stormed past us and aggressively slammed the door towards the seat we were sitting in (it did not hit us, it slammed against the armchair of the seat) DD looked at me in shock and I said oh dear what a loud bang ! In laws sat there and said nothing. This follows another few incidents of hostility, aggressive short sharp words and swearing towards me, a “push or jab” from her when I walked in front of her to grab something (well she came up from behind me quite quickly pretending to carry an object that she ‘oops nearly lost a hold of’ she has previously been violent towards DH as well. I feel like I should have told her not to be so purposefuly agressive in front of my DD, she could have easily banged her head. I know the whole “oh i didn't mean it stop being stupid would”come out with her”i am aware her past aggressive issues may be clouding my judgement here, so, am i being unreasonable to have a word?!
