Is there any point to responding to my mom’s generic apology?

I haven’t spoken to my mom in 6 months because often when I do, she says something mean or insulting and although she has told me in the past to let her know when she says something offensive, when I do, she denies it or flips it around on me to make it seem like I’m just too sensitive and nothing changes. I spent the first quarter of my life in shambles trying to appease her. She was emotionally and verbally abusive and neglectful for my whole life and I finally needed to take a break from her. I have a toddler and am pregnant with my second baby and want to heal and be happy finally with my husband and family. But, therapist pointed out that not responding to her might be a fight/flight/freeze response since it still upsets me when she contacts me.

My mom sent me a screenshot of a very generic ‘I did the best I could but I’m your mom and I’ll never stop loving you’ meme and I’m considering responding saying that’s true, but it’s the ongoing arguments and comments that I have no way of stopping that is making me keep my distance. Is it a bad idea? The situation feels like a recurring cycle and I'm just not sure the best way forward.
