[ ] I'm 24, live at my DPs mums house and have done for nearly two years but don't pay any board. My DP pays £290 board a month to his DM and I save £400 a month towards a deposit to buy our own place. I also pay £100 to my parents to keep my room at home so we can go between. Before we moved in with MIL we lived at my parents for 3 years where DP did not pay any board but I did. We both have full time jobs but don't earn a great deal. MIL has an en suite in her room and I share the main bathroom with DP, his DB and his girlfriend when she is here. Shower has been on the blink and plummer has confirmed it's dead and will be £250 to fix (it's had 10 years of use so general wear and tear). MIL doesn't use our bath apart from washing the dog once a week so I feel I should offer to pay towards the cost or ask BIL & GF to split the whole cost with me and DP. MIL moans she has no money all the time and it makes me feel awkward. I always want to offer even though DP says I shouldn't as it's not my problem. AIBU to think I should pay for the shower to be replaced? My friend says it's not my house so not my problem.
