Welcome

Sorry you’re here, but glad you’ve found us. First take a look at the Tools at the top of this page.
In the eight years you’ve been together, you certainly got a taste of BPD, but now that you’re married, you have a banquet! That’s typical, as BPD is a disorder of intimacy and now you entered into a marriage contract, the level of intimacy has increased.
Before marriage, were you living together? Combining funds and incomes?
I’d suggest that you continue to do things you did as a single person, having outside activities and interests. And keep your finances separate.
Having good boundaries is a necessity in a BPD relationship.
Meanwhile tell us more of the issues that are arising.
