Recently I've been waking up believing that I've cheated on my partner on the day prior or sometime in the past. I know for a fact that I haven't done so because I haven't been going out and I have no text threads that point at infidelity of any sort. I have been obsessing and feeling guilty over something I've not even done and I can't seem to stop. It's ruining the relationship between me and my partner as well. Initially he was understanding and recognized the fact that I had OCD, but after repetitive instances like this, he's beginning to doubt me too. I can't trust my own mind and memories anymore.
