My partner has depression and until recently he was taking medication which really helped him. It helped smooth out the bumps in his moods. In the last 3 months he made a decision himself to stop taking the medication and only told me (his partner of 14 years) after 2 months. I asked him to go back on the medication as his work is extremely stressful right now. He said he would but he hasn't and I am noticing the moods coming back, slowly but I really notice them. He doesn't see it at all and if I say anything it ends up being my imagination or my fault or that I'm being over sensitive. What do I do. I feel helpless and feel like either he will snap under the strain or it will wreck our already strained relationship. We have 3 small children so I am fighting to keep the relationship to a tolerable level but I fell out of love with him because of his illness. It was undiagnosed for at least 5 years. Help. What do I do?????
