Hello Ceiba2017,

Welcome to the family! Sorry to hear about the pain and confusion you have been dealing with. What describe sounds very similar to things many of us here are dealing with. We tend to sense something is "off" in our relationships and our partners actions, but can't quite pin it down. It can take us to some pretty confusing and hard to navigate places in life - that is for sure!
There is a lot here, so I want to focus in one thing and hope that soon other members will find time to engage with as well, but I notice you mentioning not having mentioned BPD to him. It is often said around here, with good reason, that mentioning the diagnosis (or potential one) we risk upsetting the person and it is not a good idea. That is certainly a fair assessment, but not to be taken as a one size fits all thing. I think in your case it
might be an option to present this idea because you both have experience with therapy, etc. Perhaps, as I did before I came to this site, you could just suggest he look at a symptoms list or take an online assessment. I did that with my spouse and he agreed with it immediately - that this sounded very familiar. That helped me to get on the right track with sorting this stuff out. I am honestly still not convinced of what his exact health issues are, but I do know he has some of the traits of BPD so I work with it like that.
Because of my spouses mistreatment of me at times I have had to debate my quality of love for him at times. This is something many of us struggle with and we definitely hear you! I have found some strategies to deal with this, and perhaps others can also share about theirs.
In my case I do a lot to create a loving home life and speaking to each other in loving ways to help... .not bring back the early times, but rather, create a present that has its own nice, special feel to it. We've been telling stories to each other lately about our early years, but I find they feel so distant now. Hearing them brings up some good memories, but I am sure I can never recapture those times. Instead I try to focus on making a new type of "romance" for the current era. My birthday is this month and I have a batch of birthday issues... .So, instead of being bummed out or disappointed I have embarked on a month long birthday extravaganza - though with limited means of course - and brought him along on the ride. So far it has been quite amusing and fun and will create good memories as well... .we'll see how it goes.

Take care and looking forward to hearing more from you and others about these issues!
