Two weekends from hell

Well I know my husband well enough after 11 years that it shouldn't upset me when his depression gets ahold of him but these past two weekends has been hell. I don't know how couples go through months or years of this. Last weekened we were to go see Toy Story 3 on Ice as a family and he bailed at the last minute because his mood was too bad to cope. We had a great time but still I would love to have him there with us. This weekend he starts talking about what life is going to be like when I leave him or when he leaves. I know in my head that this is just the depression but in my heart it hurts like hell. I want to be the good and supportive wife but I had enough last night because this is not the first time in our marriage he has brought this up. I told him if he felt he had to leave there was the door and I would figure everything out. I so desperatley wanted him to hold me and tell me that he was just venting. Instead he got up and told me to give him time and space to process this information. I know that once he has a job and feels secure and that he is supporting us things will get better but I don't know how I am supposed to put up with this for the next three to six months. Right now I can't share good or bad news with him and I hate the fact that we can't spend time together. I had an awesome night planned for Friday night but he never showed up because he got distratcted, Saturday the same thing. Thankfully I have this blog to vent through
