SAHP isn’t for me, but in the fictional reality where I would consider it, there would be conditions.
I would only leave my job if my partner had a significantly high income, and there would be no impact on our lifestyle.
I’m a high earner, so that would be a tough ask, but he would have to be so affluent that my wages were just a nice extra. I would not be happy to change our lifestyle or sacrifice anything (holidays, cars etc). I’d rather work.
I also would expect all finances to be joint, and a pension contribution to be made. I’m not sacrificing my future.
I would only ever consider it if I had my own pre-existing savings, or independent income stream. I would want to be absolutely sure that if we separated I had a safety net available.
I actually prefer working full time over even the idea of being a SAHM, but if it was ever a conversation - he’d have to be able to fully support all of us, to have the life we do now, and I’d need to be sure I wasn’t coming out of it worse off.
