> decided that my wife is an adult, and she can work it out with her neighbor herself.
so, the question is who needs to deal with the issue? Here are arguments that husband should:
Housing is mentioned as husband’s obligations (source: Ketubot). Rambam’s Hilchos Ishut ch 12-13. 13:5 says that he needs to provide according to his wealth. So, if she is used to live in a quiet house and he can afford such, one would think she can insist on that. But if he can’t afford it (which is quite possible with current prices), then he does not have to. Note here that for kids only minimal necessary things need to be provided, does not have to be according to his wealth.
Rambam also says to provide the wife appropriate clothing to visit her father, wedding, funerals, but not more than 1-2 times a month! So, maybe her house needs to be livable then!
13:15 Both spouses can object to bad neighbors and force a move. (can we call a bird feeder a bad neighbor because he is not considerate of others?) Also, both can object to in-laws or anyone visiting.
13:18 Husband can not force move from pleasant to unpleasant surroundings (and other way around!) So, definitely, one can not move to the bird feeder!
Also, husband is obligated to pay for long-term medical care. So, it is just a smart idea to deal with the issues before the wife goes completely bezerk!
