Hello Taralli and a warm

Glad you found us and reached out for support. When BPD is in the mix, that makes all kinds of "normal" relational interactions more challenging, and then "challenging" relational interactions can be through the roof. BPD plus finances is not an intuitive combo to deal with effectively.
It sounds like the two of you aren't married? How long have you been together? Have you comingled finances already, or are you maintaining separate bank accounts etc?
Do you want to be part of the project, or do you want it to be "his thing"?
We can run ourselves in circles trying to "get them to see" or "get through to them" about their choices.
Fortunately, while we have 0% control over anyone else's choices, we have 100% control over our own

In an ideal world, would you choose to be involved at this level:
I think its a cool project but I find it risky for a first time home owner and even more risky for somebody like him who has no free time for anything (he works 7 days a week) and no social skills or tact (I'm the one who makes all the calls, negotiations, realtors, etc.) We are at a point where I can't question anything about this house without being accused of being negative which is completely unfair considering he is being delusional and really emotional about this purchase.
Fill us in when you get a chance, and again, welcome;
