Sorry this is my first time posting here so not sure if I'm in the right place.
I have been with my partner for 18 years(not married) we have a ds 11 and a dd 9. When we first got together everything seemed great. He was my first boyfriend so didn't have any experience with what's right and what's not. After about a year of things going well things started to change in his behaviour like getting onto me for things that's minor but making it a big deal and carrying it on for days or simple name calling. But I shrugged it off thinking maybe he was just tired or I had done something wrong. Things carried on like this for a while until I told him I had enough and wanted to separate and he promised he would change so I stayed. For a while things were good and I felt like I made the right choice in staying. We had the dc and things carried on being great until about a year after our dd was born. I started noticing more signs of him slipping back to his old ways and started with the name calling again. My family adore him as they don't know anything of what's been happening but he always has something bad to say about them. The trouble is more with my dad as he can be quite immature and full on(I suspect adhd but not diagnosed) but his alone so I try my best by him. We lost my beautiful brother 3 months ago and things have been tough but my partner said he would take my dad to the cemetery to make him aware of where it is so can go when he wants. Fast forward to today and we were on our way to pick him up and partner exploded on me saying I was forcing him to take dad out and forcing him to see someone who he said is an idiot who can't live his life without me. I have offered to go alone on a bus but he always ends up saying we'll why don't you want me to take you (I don't drive but taking lessons) he was swearing at me and telling me he does too much for me when I'm the one who keeps the house going and goes shopping and does basically everything the only thing I ask of him is to take me shopping if possible. He is a good dad but doesn't understand treating me this way is not good for the kids to hear. He has said tonight he will find someone else and I will be regretting putting my foot down because I'm always in the wrong and have done everything wrong to him. Is this normal to make someone feel this way. Any advice greatly appreciated
