I feel so foolish, I really do. I'm doing the best I can to take care of myself, took a walk yesterday and going soon this morning.
I think back to the beginning of our relationship over 30 years ago when we were youthful, full of hope, the promising years ahead and I'm so sad it turned out this way. He was/is my husband and I can't comprehend how and why he has treated me so poorly if he really loved me. I know, he has BPD, it's the disorder but... .
Awake, I am so sorry this happened to you, but I want to reiterate Rose Tiger's words that it is totally understandable -- please, please don't feel foolish and don't beat yourself up over it. It happened, it cannot be undone, and you need to get back on the horse and move on.
The last part you wrote here about thinking back to the early part of the relationship and how good it was is a piece I have been/am/and will be struggling with for some time. I am only on day 6 of leaving, so it's pretty fresh. Some friends came by last night and they get that I'm in a hard place BECAUSE there were so many good times and he DID (does) have such a good side to him. They know I don't hate him - it's not like "Oh, thank God I'm rid of that d**** bag!" They seemed to get (without me going into a breakdown of BPD) that we had a long "honeymoon" period, I ignored red flags, his "issues" surfaced a few years ago, and it's been downhill since. Eventually, I told them that it got to the point where I became his trigger. I told them his thinking is disordered and gave some specific examples where he has said increasingly irrational, paranoid things to me. For me, it's been helpful to reach out to trusted friends and share.
I tell you this to let you know I understand
the pain of trying to reconcile the GOOD in the man with the inner demons. It has been the most difficult part of the whole process for me too - how could this man who started my car daily for years, made my coffee, kissed me awake, wrote me love letters, massaged my feet, would do anything for me etc. etc, ... . how did he turn to such a monster? Understanding BPD helps, but my brain still has a tough time wrapping around all the facets of the disorder. I am working on it!
I simply could not deal with the demons any longer and left, and so did you. That is a show of your courage and strength! With us, the good certainly became less and less as the demons came out more and more. I was so guarded that I stopped being myself... . maybe years ago? I have notebooks full of things he's said to me in rages, etc. and I bet you do too. I have felt rather strong this week yet have had lapses already -- seeing a picture of him in happier times, memories, regrets.
I am forcing myself to go through these notebooks - a couple nights ago, all I did was read a half page script I had written of what he said to me in a rage from about a year ago, and it 100% validated that leaving is right. It was full of things I would never say to a worst enemy - and he was supposed to love me! And, the next day, he would act as though it never happened, while I was left with a deep wound (?). I put it away and didn't need to read more.
So, don't regret the relationship - he is not a bad man - focus on the disorder. The disordered behavior is so toxic that you need to be away from it. You did the right thing. Pull up the BAD memories and the things he did/said to you when you need reinforcement that your choice was correct. Easier said than done, but work to let go of who he is/was dating and focus on you!
I'm glad you took a walk and went to a movie - those are great choices to make you feel better. It made you feel horrible to drive by... . try not to do that to yourself.
You are further in your journey than I, and frankly, I anticipate that I will do some similar things. I've read lots of examples of backsliding on the forum and expect that it's part of the process. Just being away from our BPD is not the end. It's the beginning of new growth... . just try to see it like that and please don't be too tough on yourself! You are a strong woman to have made the decision you've made - you are away from the chaos, constant drama/turmoil, pain. Life will be better, and I bet it already is.
You are going to be ok - a survivor! *apologies that I am so long-winded
