Sister in law acting weird?

Hi so to start off I've been married for 4 years.

So we have always been friendly and chummy but for sometime I feel something is off?

For starters when we all meet at family hangouts she comes hugs me thats fine... a few times though :-

she would come hug me and press her chest against my shoulder or head.

One time I was sitting on a sofa she watching tv she sat next to me we were chatting and mid convo her hand rubbed my leg

Once she was showing me her art work I was like "this is really good you're a pro" and she giggled and randomly rubbed her finger on my lips.

A few times she said "we should hang out".
She asked me to help her join my gym which I did and it was alright.

I got her takeaway once from her favourite restaurant. 5 mins later she sent me a long rude message saying "wtf are you doing? This is where I work. This is inappropriate". I immediately apologised and made it a point to STAY AWAY FROM HER.

At later family events she was there tried to talk... I avoided by making excuses.

Few months later at a wedding I was sitting, getting drunk when she shows up to ask what I was doing... I said "nothing just chilling".

She sat down uninvited an apologised profusely, said she was out of line was having a hard time at work etc etc. I didn't much care and was tipsy so said "its ok whatever, sorry if it bugged you lets move on". She walked me to my room, held my arm.

So as I came closer to my room she just hugged me and said sorry again. I said "its ok, leave it. She smiled and said "thats sweet" then she left.

I messaged few days later to which she said "I dont think we should talk anymore"... I was like wtf I thought you called truce?

She then told my wife she doesn't like me around and I was like "Fine fuck that I dont wanna talk to her either".

Months have passed, she still sometimes comes and says hi and tries to start a convo. I cut it short
