I am sorry but I think this is quite offensive -‘and I would be curious to see if this poster typed the same things if they were faced with similar predicaments to the OP and others.
Children might need their “mum and dad” but there shouldn’t be elastic and forgiving criteria for fathers, and unforgiving ones for mums who by default shoulder a lot of the work.
there are huge swathes of women who enable terrible behaviour from dads by shrugging when they hear of non payment, CMS avoidance, etc by saying “you shouldn’t have had children with them”. Again, placing the blame and responsibility on other women.
I think why this situation doesn’t change is due to what seems to be the continued “right” of a man to lose interest, leave a family, and then resent the existence of that family despite having been active in its creation.
that resentment leads to complete disinterest when they inevitably meet another woman, who in turn is happy if that father keeps that money in their “new”household. Therefore reinforcing the situation that an “old” family is a financial inconvenience.
This is how our society reinforces things. While I am very lucky I am with my original first partner and now DH, I experienced this from my father, and I saw it in countless relationships years later as an adult.
