My ex is a high earner but since we broke up has been awful and withdrawn promises he made ie paying for childcare or even paying half. I get 370 a month from him but my maternity finishes soon snd childcare is going to be 1200 a month. I earn 2300. I don’t know what to do, losing my job could mean I never get back into it so just packing it in isn’t ideal either. So drained.
