For context, I have been free of suicidal thoughts for years now, but after going through a super rough patch these past few months, I've started getting them again. It's nothing intrusive, and I've been through this before, so it's pretty easy for me to dissuade them quickly. I can say with certainty that my life is not in danger, and I have no serious thoughts of harming myself. 

Next month will be my one year anniversary with my significant other. It's by far the longest relationship I've ever had, and I'm very happy with her. I've told her that I've been struggling for the past few months, but I've decided to withhold information about my suicidal thoughts for now. I trust her, and I want to be honest with her. I know that she will be supportive and want to help me if I tell her. I also have a terrible track record with sharing my emotions, I've always been someone that bottles everything up. I'm also afraid that she will feel guilty or feel slightly responsible if I tell her, and I don't want to hurt her feelings. 

I want to talk to someone. I want to talk to her. I'm just worried. Advice?
