The reason I asked the above questions is because OCD can be intrusive and controlling not just to the sufferer but for those around them too. Your partner may well be a lovely person but his OCD is controlling him and therefore it is controlling you and your children too. This is not healthy, which I suspect you already know.
I don’t know if you suffered with anxiety before, but I imagine tip toeing around your partner’s OCD must have your anxiety off the scale. You will be appeasing him because it is what’s easier and perhaps keeps things calmer at home, but long term this going to end up hugely damaging to your children and it will be effecting them greatly now. Small children should not have to live with such anxiety and limitations to their life.
Since it seems like you two got together at such a young age I can imagine that it’s hard to think of your life being any different, and must be very difficult and scary to contemplate it being any other way. You’ve grown so used to living the way you do now it’s become almost normal, but you also know that is not normal or healthy for you and your children.
I couldn’t be more sympathetic at your partners plight with OCD, I suffered it horrendously myself for around 2-3 years after going through a very traumatic time. It can be very difficult to tackle and although you can rationalise things the habits of OCD die hard, and some never go away.
All the above said I have the most sympathy for your children and for you. Lots of people have commented about the statement you made about if your youngest had been a girl and have found it abhorrent. However, I think that this is something you’ve told yourself to give you some emotional distance and as a way to excuse your partner. Speaking plainly and honestly I really don’t think anything would have been different at all, such is the intense hold your partners OCD has on him and by default you and your children.
As mumsnet have kindly and helpfully mentioned I would also urge you to reach out for help and speak to women’s aid, if for no other reason that to at least get some objectivity and perspective on the situation you and your children are in. Not all abuse is physical, not all abuse is a verbal screaming match, some abuse is quiet, insidious and can go almost undetected which can make you doubt yourself, please don’t doubt yourself, you are suffering and so are your children.
All the best 💐
