Unhappy in marriage, but staying anyway?

[Applepearbear]

It's easy to think LTB when talking about relationship problems, but sometimes that's not an easy thing to do. I'm in a less than blissfully happy marriage, but it would be difficult to leave.

Just wondering if many stay in marriages even though they're unhappy?

Not married but yes, I am not happy but staying. I did leave for a few months, but the disruption meant DD stopped sleeping, arranging contact was a nightmare and was costing me 60% of my Universal Credit entitlement, DP was unemployed at the time so no maintenance, had to move hundreds of miles away to a town with very little in the way of job prospects, even for low skilled work that I can do. I blew through my savings/running away fund which had taken me years to build up as I had to wait 10 weeks for my UC to come through due to their incompetence. So I'm back in the family home, DD is much happier and DP is now working so thankfully I see him less. It's utterly soul destroying to be honest. I reckon it will take me another 5 years to be in a position to get out again. If I came into money/won the lottery I would be gone the same day.
