sparewheel, who sorts out the finances and ensures the bills are paid? do you share it equally or not?
I ask this because IME this is another burden, especially if money is tight. It is also a reality check. Is your partner under the impression that any wages of hers contribution would not make much difference to finances?
If you are struggling to pay that massive mortagage and you are the one balancing the books, it can be a source of huge stress and take up lots of brain space, which will impact on your ability to be a good employee and parent. And make you personally unhappy as well, of course. (I have to disagree with frayedknots view of this).
If you partner is not involved in bill paying and is ignorant of where the money goes, I think you are having a rough deal. At the very least, can your partner take a big share in sorting out monthly finances? A worry shared is a worry halved, as they say.
When my ds1 was a toddler, I was the only breadwinner and also the only one to sort out the bills. It caused me untold sleepless nights. I had two jobs, one from mon- fri, another (running a market stall) at weekends.
Crunch time arrived when:
I woke up tired every morning and frequently forgot what job I was meant to be doing until I had checked the date.
I was at my stall one day and had a panic attack and heart pains and couldn't move for 10 minutes.
My husband phoned me at work from the park where he was enjoying an afternoon with our son, along with a preditory single female acquaintance of mine (who also happened to be trying to start an affair with him).
In my case, I had a solution. True, we lived in London, but it was possible for us to move to a cheaper part of London, reduce our mortgage and release some equity in our house.
If this is an option open to you, and you have reached breaking point, take it, is my advice.
