Friend acting overly affectionate and inappropriate

I’ve had the same best friend on and off since kindergarten. Always been so close, did everything together. We’re both 30 now so we’ve had a lot of ups and downs through the years.

We both roomed together in college. While we were living together we hooked up occasionally for about a year. I was 19 and experimenting as was she. We both agreed during that time that it was just for fun, that we didn’t have feelings for each other and we didn’t want a relationship. I was incredibly clear about that. I ended up meeting my husband the following year in college so we stopped hooking up. Once we graduated I moved in with him. We got married a year later and my friend never got over it. She refused to come to my wedding. She acted like my husband was this terrible person, which he isn’t, and tried to turn our mutual friends against him (because she was so jealous I was with him). Thankfully all my friends and family knew he is a great guy and never believed her lies.

We didn’t speak for 4 years after that. In that time my husband and I had three kids. Out of the blue one day she text me, apologized for everything and asked to meet up to talk. After taking about it with my husband and getting his approval, I agreed, we met up, she was in a much better place and so I accepted her apology. She had her own boyfriend by then and everything was good.

Fast forward to now. She’s no longer with her boyfriend but we’re still friends. I met up with her yesterday after not seeing her for months because of quarantine. When we met up she was acting SO WEIRD. When I got there she asked for a hug which I gave her but it lingered a little bit too long for my liking but I figured maybe she just missed me so I let it go. We were hanging out and I was driving to the store with her and my kids (my husband had to work) to get supplies for dinner and she grabbed my hand while I was driving and tried to hold it. In the couple way!! Again I was so uncomfortable so I politely took my hand away after 5 seconds. When I took my hand away she PUT HER HAND ON MY UPPER THIGH. Then I stepped in and told her how uncomfortable she was making me and told her to stop. She apologized and said she just missed me so much and her intent wasn’t to be “sexual” and I was reading too much into it. I reminded her that I’m HAPPILY MARRIED and don’t want to go there again and reminded her that no means no regardless of context. She agreed, apologized once again and I let it go.

We get home, made dinner and start watching tv. Everything was fine we’re just chit chatting and she started going on about how much she’s missed me and the kids. She then was “joking around” and was trying to get my 11 month old to call her mama. I told her how weird that was and she told me I was being “so stern” and needed to lighten up that it was an obvious joke.

After that we just watched the movie in silence. We’re sitting eating our food and she asked me why we haven’t cuddled yet. I told her I wasn’t trying to go there because I’m married. She then said, since when is cuddling with your friend sexual? She then lies her head on my shoulder and tries to hold my hand and when I pull it away she starts rubbing my upper thigh again! At this point I was over it, I told her how fiercely uncomfortable she made me the whole time I was there and how I don’t think we should be friends anymore. She then told me I was acting weird and those things are normal for friends to do but I’ve become “weird about everything since since I got married”. She asked to hug me before I left and I told her no and left. She sent me a text when I got home about how I made her feel so bad for just trying to be my friend and how I was the one who made things weird by denying her “platonic affection”. I told my husband everything later that night and cried because I felt so violated. We agreed together that I should cut off all contact and not see her again because she wouldn’t listen to me everytime I said no and overstepped so many boundaries. Am I overreacting? Am I right to cut her off? What would you have done?
