If I had not read your latest response, my advice to you would have been to talk to your boyfriend about this. Although I have only been dating my boyfriend for about 2 years, his depression has been a major part of our relationship from the beginning. However, we both know that this is his battle, and not mine. To me, it seems like the worst thing I could do is leave him to suffer while he is at his worst. My story is similar to yours, however, my boyfriend only realized that he was depressed after we started dating. He seemed perfectly fine and happy at the beginning of our relationship. However, I started noticing a change in his behavior. He became very hard on himself, and always had low self-confidence. He didn't want to participate in many things, and I could tell something was wrong. I suspected it was depression, but hadn't brought it up with him. Fortunately for the both of us, he came to this realization on his own. We sat and had a long conversation about it, and he knew that he needed to seek medical help. He began seeing a psychologist, and I could see a major improvement. Unfortunately, his depression has started up again, and possibly even worse than before. I am on here seeking the advice of others, and telling me to leave him is not exactly what I had in mind. The only thing I can tell you is that listening and talking are key. He needs to know that you support him, and that you will always be there to talk to when things are bad. Though my boyfriend has his lows, he says that he feels so much better when I am around, and that is all I could possibly ask for. This experience has taken it's toll on me, but it is very unlike me just to give up. I know I love my boyfriend, and I could never give up on him. Communication is very important, and now that you have opened that door, I only hope that the road to recovery is underway.
