Depressed at the thought of living like this forever

[lovelydayyyy]

Split up from DH a while ago. We have 2 dc. Moved in with my parents but it wasn't working. So moved back in with DH (still separated) so that more stable for dc and we could both have shared care of the dc instead of swapping them about etc. We rent house from the council. Both earn ok wage which we keep completely separate now.
Neither of us can afford to move out, just about get by with what money I have now, no way I could afford a deposit for a house and the thought of living like this is so depressing. Everything in the house is shared from when we were living as a couple.
How have others managed to move out when they have separated with children. If I didn't have dc I would move in with parents and save

@ReganSomerset the OP has already stated that she does the majority of childcare so not sure how her moving into a house-share would work without the kids.
I didn't mention house-share.
The OP has already separated from him and those suggested they should 'make it work' aren't helping.
Suggestions have been offered to its up to the OP what she does now. She doesn't want him to move out cos its 'not fair' and she can't afford to move out so not sure what we are supposed to advise.
