Did I overreact by ending it

This is all still fresh so sorry for the word vomit but I ended it today after expressing concerns again about the lack of one on one time together and him responding that it’s a difference in energy levels - he repeatedly says he has more energy than me and if I only had more energy to stay up late and do more I wouldn’t find it all so hard. I completely snapped - I felt he was blaming me for all the baggage and complications he comes with and instead of validating that made it my fault for not having more energy.

He has a volatile ex and two young kids in the picture. Not to mention the other ( stable ex) and the older kid he has with her. So three kids and two exes in the picture. One ex seems fine the other is absolutely unhinged to the point of showing up when he has the kids and threatening him.

He’s also 57 to my 40, so an age gap.

He works long and changing hours in hospitality - so we had no weekends together alone as that’s when he has the kids and often weeknights were out too because that’s when he works late in hospo.

He was a threat to my stability I felt , the kind of guy with volatile exes, legal bills for those exes, the kind of guy who thinks it’s okay to run red lights on a Vespa at 2am because no one else is around, the kind of guy who thinks it’s ok to light and leave a bon fire to burn out unattended on the wooden deck of the home I bought and am paying a mortgage on and to mock me for being too safety focussed when I say I’m not leaving a bonfire unattended overnight while I sleep in my backyard.

Of course easy for him to put my house at risk when he isn’t the one who owns it, he rents. I reminded myself that his two youngest, who are old enough to know better, tried to feed chocolate and Lego to my rescue dog. He has many wonderful traits but after all I’ve worked for all I’ve built I got sick of the threats to my stability and being made to be seen as a low energy killjoy when I reacted to those threats.

There’s so much more but I’m hurting at the moment so much
