This is a great and very important post. I was in a relationship for 6 year with someone who had several mental health issues. Unfortunately it didn't work out, but it's given me a lot of perspective on this, including where I was, and was not, supportive of my partner.
The biggest hurdle to a relationship with someone who has mental health issues is how willing they are to get the support they need. You as a partner cannot be both their lover, their partner, their therapist, and their primary means of support. It will send the relationship down a toxic rabbithole that will be detrimental to you both. As much as you want to do everything you can to support them, you can't force wellness on anyone; they have to be ready to get the help they need and put in the work.
People with mental health issues deserve love and all that comes with a healthy relationship. It can be scary for many and it's ok to recognize maybe you aren't capable of supporting them properly. I'm glad it sounds like you are in a loving and supportive and overall healthy relationship and that you have been able to get a handle on your issues.
You took the words right out of my mouth.
Thanks! Yes, bumpy road at first but there seems to be a fresh uncluttered roadway for the forseeable future :)
