I'm experiencing this right now from the other end - I was diagnosed with complex PTSD last September. I've always had some minor PTSD symptoms that were manageable, but for me, the trigger that caused the PTSD to finally emerge full-blown after all these years was because I had fallen in love. You see, sometimes feeling close means feeling vulnerable for us who have complex PTSD, if all of our previous experience in life has shown us that being emotionally vulnerable causes us to be abused by the people who love us, then intimacy with a loved one is very difficult. For me, this intimacy with my boyfriend set off months of flashbacks.
I have been with my boyfriend for 2 1/2 years now, and I have thought for most of that time that I could see myself marrying him. I love him for who he is, and respect him and want to be the best girlfriend/wife I can be for him, because he deserves that. However, my emotional flashbacks were becoming so intense that just the simplest innocent comment from him would cause me to spiral into a deep pit of self-hatred, suicidal thoughts, some intense self-harming, and complete inability to speak or engage in any sort of logical thought. During these times, I see him as my angry, controlling, and emotionally abusive stepdad. I can't trust him or speak to him...I can only see evidence that he hates me and wants to hurt me....but of course this is not true. This makes him feel awful. In fact he loves me very much and is very kind-hearted. This situation has happened n our relationship probably hundreds of times now. I have always been so appreciative of his support for me, but it has worn on him immensely. I realized how bad it was for him when he began dissociating after my suicide attempt two months ago. He told me how much he loves me, and that every day he worries that I will kill myself. It is quite possible that us remaining together during the toughest times in my PTSD have been traumatic for him, and he is experiencing the effects of that trauma. Also, I felt like I needed him to be there with me to keep me alive. That's extreme codependency, and it's not good.
We have now "taken a step back" from our relationship for the past three weeks. I cried the whole first day and just wanted to end my life. I miss him every single day. I love him so much...and I want him to be happy. If he stays close to me right now while I go through intensive PTSD therapy, I will most likely continue to be plagued with these debilitating emotional flashbacks that make me want to kill myself, and he will still not be able to help me. Him, my friends, family, etc are not capable of helping me - God and my therapist are the only ones who can help me heal. After that first day not speaking with him, I actually felt a tremendous feeling of relief and freedom. I am no longer investing my very scarce amount of emotional energy into the relationship with him, and as a result, I am having fewer flashbacks. Fewer flashbacks = less self-harm and a lower chance that I will attempt suicide again.
I love my boyfriend too much to get close to him; Throughout all of my life before I met him, intimacy was coupled with abuse. Right now, I am unable to be close to him without feeling abused, and wanting to die as a result. I can't keep doing this to him - I must get better before I can become intimate.
If he loves me and misses me, then why can't he be with me??
I hope that reading this perspective from the other side - as a PTSD sufferer - sheds some light on your questions and hurt feelings. Best of luck. I know that being intimate with someone who has this mental illness can be very painful and confusing.
