Realistically the op is paying £450 per month to her Dp.
Expenses are £1100 that means Dp was earning £2400 + £250 + all food from op so income £2650 less £1100 expenses less even another £400 per month extra expenses and no food to pay for means the Dp had £1150 per month to spend and save something but actually spent the lot each month and sometimes ran up more expenses.
If op and her Dp pooled their money as MN says should happen they would have a joint income of £3250-£1500 expenses and £250 for food expenses. Then splitting the rest between them would have meant op and Dp would have kept £750 to spend or save as they wished each month
Or they could have put £300 per month away and still had £600 each to spend.
Instead the Dp is asking op to cover his expenses with her savings but offering nothing in return.
As I said the Dp could after exhausting ops savings could tell op to leave and she wouldn’t even have a deposit for a rental so could make op homeless.
For those saying if you move into someones home (at their request when you are in a relationship) and pay towards the bills and then yes you should be on the deeds otherwise you are exposing yourself to financial insecurity.
I would presume op could find somewhere to live on her own and have money over like before if they did split. Her income would rise as she would be considered as a low earning single parent.
For those saying the Dp isn’t earning a lot I run a much larger house, 2 teens, 5 cats, 1 Dp, 4 cars and a van on less than the op and her dps combined income. I also pay for holidays as well.
I think £2650 and no food to find money for, for a flat and 1 car is more than enough.
Interested in what redundancy pay out there will be.
Will he ask op for her contribution immediately or will he spend his redundancy quickly first.
