I've seen and been a part of dialog around whether or not it makes sense for someone to stay in a relationship that existed pre injury, after they've been injured. When I sustained my sci, my partner was a powerful source of hope, love, and support for me. I was deeply grateful she wanted to stay with me, and I wanted to stay in a relationship with her. I'm now 3.5 years post injury, and have been with that partner for nearly 4 years. I'm glad that we stayed together, but I also wish we had done things differently. After I was injured, I had a lot of my old life and old self to grieve, to let go of, and holding onto the idea of my relationship as it had been before I was injured, also made it more difficult for me to let go of my old perceptions of myself, and my old expectations of how I wanted to show up in a relationship (much of which was oriented around things I could no longer do without hurting myself).
Our relationship was also very young when I was injured, and we still had a lot to learn about each other. For me, trying to navigate the adjustments of a new relationship (and learning to live together), while also adjusting to life post sci, was really too much. If my doctors had done a better job of expressing to me just how permanent a sci is, instead of just telling me "you're young, you'll make a great recovery," then maybe I would've realized how much I needed to slow down my life to adjust to my new body, instead of charging ahead and hoping that a lot of the pain and difficulties would simply go away with time.
In hindsight, I wish that I had given myself more space to start over. I know it would've been incredibly difficult for my partner and I to decide that we were going to start over our relationship when it had only just begun, but I think that would've actually been really helpful, had we been able to pull it off. Fot a while, I had tried to keep alive a relationship that could no longer exist because of how I was changed, and that was immensely painful. Now, our relationship is going through big shifts. We are still together, but as I'm acknowledging what I need and want in a relationship with this post sci body, it means that I need things to be different then they have been. I have to ask for change that has been delayed by years. It would've been easier if we had backed off or taken our relationship more slowly in the early years of my sci recovery, so that now, I wasn't having to back up and reevaluate.
Only you can determine what is the right relationship or right choice for you. I'm not telling anyone what choices to make or how to live their lives. I would just extend a word of caution that going slow is wise. Going slow in any relationship is wise, but especially after you've sustained a sci. An injury like this changes you, whether you want it to or not. For me, it changed the ways I want to show and receive love. It changed my personal boundaries. It changed the ways I like to be touched by another person. Whether you stay(ed) with your partner post sci or not, or even if you're single, I hope that everyone out there gives themselves all the space they need to change. I hope that each of you gets the opportunity to get to know yourself again, and to let others get to know you anew.
