BIL has asked if he can stay with us for 3 days during the week. I really don't want this, but wondered whether IABU, especially as I would allow my own brother and SIL to stay no problem. He wants to stay because he is attending an event that is 15 miles from our house (so just using us for free accomodation).
We have DCs aged just 4 and 1 and we do have the space for BIL to stay.
BIL is a very strange person, he's 45 and throughout his life, he has slept with hundreds of random women. He never settles and every time DH sees him, he has a different one on his arm. "Relationships" usually last 1-10 days for him, he is a sex maniac. I am no prude, but I find his behaviour dirty and disgusting particularly as he gloats about never using condoms. (These women are sometimes likeminded, but plenty of them want a relationship and he breaks their hearts) Perhaps I am judgemental, but having slept with hundreds of people and been careless with sexual health, I find him ick and dirty and don't want him staying and sharing our bathroom etc .
He lives 200 miles from us and I haven't seen him for 3 years. He never keeps in contact and doesn't care about my DH, me, my kids or even his own parents (my PILs, who are very nice and I have them to stay whenever without a problem). My kids have met him once and he will be imposing just for the free bed and bringing a random woman who I have never met and who I will probably never meet again. I just don't think it is appropriate to use a family home as a doss house for strangers when kids are so little.
So tell me, AIBU and if not, what reason do I give for not letting him stay?
Just to add, I am quite sad about all this because everyone else in my family and DH's family is close and we all care about eachother. I sort of feel I am perpetuating BILs behaviour by not letting him stay, but I don't want him here.
