Greetings.

Moving in with a person you would like to nest with for a "civilian" has several issues. A practical side and a romantic side (and every day physical side). If you do not have the practical side aranged ahead of time the other parts will start to cause stress.

If we add in an untreated personality disorder I think it would be similar to Russian Roulette. Please take care of yourself and your relationship by getting a treatment plan. As it will help you with stress and suicidal ideations.

Please involve your BF in the process as he will need a "buy in". Other wise there is a chance of alienation on his end. And frankly if he does not want to get involved he is not the one. And you have avoided a mistake before you move in together.

I wish you all the best as this is a big step for anyone with a personality disorder.
BTW I have diagnosed BPD.
