This is a long one sorry. Been with partner for 14 years. Kids but not married share a mortgage he’s the higher earner, I have a job around my children as I do school drop off pick up and the activities after school. I do all their medical dental stay off work when they’re poorly. He normally works a Saturday so I do a club in the morning then whatever they want through the day eg park play centre relatives or friends houses. He’s always been a drinker but it got worse two ish years ago. He drinks everyday starting around 4/5 in the evening. I have recently started counting his units he drinks beer and roughly 75-85 units per week. He’s always had an angry side to him, but he could say something mean shout then be nice again for a few months etc. the last year he got worse he was drinking more, and started his own business which wasn’t the best choice for him. There were times were he would say nasty cruel things to me but very angry. In the spring I asked him to stay the night at his mums house as he got too for me, the next day he was texting me very apologetic etc came back home. But wasn’t too sorry once home, eg needs to apologise to one of my family members after horrible remarks about their children but won’t do as he thinks he was in the right. I’m absolutely mentally exhausted with him, and he’s giving me anxiety, I’ve noticed he hasn’t been brushing his teeth! The thing is, he has more money than me all the finance is in my name, he is self centred and can be extremely false in front of people, loves acting like the family man does everything type person. So if we did split I think he would try for more days with the children just to look in front of other people. When he slept at his mums in spring all he was bothered about was his mum finding out and to make sure we didn’t tell her, she was away on holiday. He’s very loud and over the top with the kids in front of other people. Since spring, he tried to look like he does more eg started taking our eldest child to high school every morning. (when they’ve always got the bus) some of the behaviours he’s had- my stepmums funeral propped the bar up all night and wouldn’t watch the kids so I could chat to relatives, shouts and denied it when I asked him about this, asks why I’ve been so long eg taking child to swimming lesson or if I and try and get to the gym myself, but in a certain tone of voice. Likes to shout at me in the car a lot twice he sped the car up said it was fault for winding him up. All of this I have no proof of just my diary I started jotting down dates. I also have two or three TikTok videos my eldest child made about dads drinking so I have saved these- I removed them off Tik tok etc and spoke to my child about this. If I do leave him, have I no say as to when he has the children? Should I seek legal advice?
