Truth #1- This was not your fault, and there's nothing you could have anticipated to make this turn out differently. I'm sure you made mistakes just like we all do, but you can't beat yourself up over that. You did the best you could and had no idea what you were dealing with.
Truth #2- He's sick, and instead of getting therapy he's using drugs/alcohol to wash away the pain. That's no way to live and it never ends well. He has to choose therapy though, choose to actively get better, for a chance to overcome BPD struggles.
Truth #3- If might hurt like mad since the band-aid was just ripped off, but going no contact is generally a good tactic to escape the never-ending cycle. If you did reach out to him, he'd blame you for all of this, then he'd beg you to take him back, then he'd blame you some more. They call it a push-pull dynamic and because he's highly unstable at the moment, you'd surely get his absolute worst. So as much as this hurts, it's a blessing in disguise. Block him on everything ASAP.
Pook your reply to my post was like getting a lungful of air after holding my breath as long as I could. Someone got me. I feel so isolated and alone right now with my pain because others in my life can't fathom why I am worried about him, and why I miss him so much, while also being so relieved he's gone that I feel like I'm finally living in the "real world" again. The two emotions are in such conflict, they are why I tear up when I think about it.
Truth #1 - I know this deep down in my core. I've just been in survival mode for so long. Survival for me, for him, for the relationship, for everything. Just getting through each day was sometimes a knock down, drag out, battle. It got worse recently but it was just getting piled on so hard that each new day felt harder than the last, so you lose perspective on how bad things are getting.
Truth #2 - As I've read on here from others, it's very hard to get someone using substances or alcohol with BPD to understand how much worse it's making things. He was drinking a lot behind my back, having "a few beers" in the open but slamming 3-4 when I wasn't around in between. Up until the very end, I had no idea BPD was what he was facing, so I just took it as he was changing due to the constant intoxication, but mainly because of me, because I was the reason for all good and bad things to happen to him. I asked, begged, pleaded, put my foot down, and all that about the drinking, he wasn't having it. He leaned into it harder the last few months, pushing me to drink with him, and not just a beer but to drink heavily with him. When I explained to him each time that I have no desire to do this, I don't enjoy being drunk, he would just belittle me, insult me, call me a "pussy" for not wanting to drink. I hope he can get help. His release after being incarcerated for the final blow up we had, mandates he enter a drug/alcohol program, and get a thorough psych evaluation. He's been a steady marijuana user for as long as I've known him so getting off that and the alcohol is going to be tough, for his sake I'm hoping he completes the program and doesn't go to jail.
Truth #3 - This is the hardest one for me. Luckily he has yet to reach out or try to contact me. Part of his release/plea deal is he cannot have contact with me or come to our home. I extended that with an order of protection which caries a heavier penalty for initiating contact. This insures he won't reach out to me, and if I reach out to him, it negates the order (to my understanding) so I'm motivated to not do so. It's so hard because I am so worried about him and want to make sure he's OK. This is sadly the same theme that kept me with him for so long, my need to protect him and make things "OK" because he's had such a hard life. I am painfully realizing that nothing I was doing, could've done, or would do in the future, would've fixed any of this. He was always headed down the destruction path, I kept prodding him in the right direction to leave that path but he was just drawn back to it no matter how hard I tried.
My biggest fear is not him, it's myself. I am worried I'm going to miss him so much that I will break and contact him, reach out to him, try to fix him again or try to "make it better for him". Today, that is not something I want to do. I hope tomorrow it's not as well. I struggle with wanting to know how he's doing but also not wanting to have this back in my life. I hope with time that feeling of needing to "be there" for him will lessen.
