Ever feel like it was mistake getting pregnant?

I’m a mum of two sets of twins and im 25 weeks pregnant with a single baby

I’ve been with my partner for 5 nearly 6 years and since being pregnant things haven’t been the same all we do is argue all the time

Things are so bad between us now to the point we are splitting up because of it!

I sometimes feel like having this baby is a mistake I also feel like the kids would be better off without us both cos they deserve parents who love each other and not argue all the time
