I'm shortly due to leave my rental property to move in with DP who already owns a property. The plan is to live together there for a while and if all goes well, we will rent out his place and purchase somewhere together which is more suitable. We are in central London so DP currently rents out one of his bedrooms to a lodger (he makes a lot of profit from this), who will be moving out when I move in.
DP has implied that he expects us to split all outgoings for the house 50/50. Having never moved in to a partner's home, I'm not sure this is right. Without question I will be contributing 50/50 to all of the household bills, council tax, food shop etc. but part of me feels uncomfortable about essentially paying half of his mortgage as 'rent'. AIBU?
Also, when I move in we are needing to covert the spare bedroom to an office space and storage area for me e.g. desks, built in wardrobes and drawers for my things. DP has mentioned when "we" buy these things which again implies 50/50. WIBU to expecting DP to fund this since it's his property and in the event that things didn't work out, he would benefit from them i.e. they'd remain in his property. Thoughts welcome as I'm new to this!
