In short, my partner probably has a lot to be depressed about - he is a widower, left with full time care of 2 primary school-aged children, found out his marriage wasn't what he thought it was after he was bereaved, had to give up his career which he loved and worked so hard for.
When I met him, he seemed to have overcome a lot of his problems and was in a positive mindset about the future, about what he wanted to achieve and what made him happy. We had a loving, happy, fun relationship for a year and a half, and the kids and I had forged a caring relationship too. We had a lot of hopes and plans for a future together as a family. But since the start of this year he has hit rock bottom.
I just don't know how to be supportive when I am struggling myself. He is so completely different to the man that I met and fell in love with. He keeps saying he needs 'time on his own' (we are long distance so he just stops texting / calling / says he doesn't want me to go to his house at weekends). So there will be a period of a week or two where we don't speak at all, then he will get in touch with some kind of revelation. So far the varieties have been:
a) he wants to break up
b) he wants to get married, took me shopping to look at engagement rings
c) he wants to move him and the kids up to where I am by the end of the year, and I should tell my landlord that I don't want another year-long contract
d) he wants me to give up my career here and come down to him for a year to see how things go
I understand he is confused, depressed, doesn't know what he wants anymore or what will make him happy. But emotionally I'm a mess - I never know what he is going to say to me next, never know whether the man I talk to will be my old loving caring partner or his new depressed self who at times is so cold. It's got to the point where, if I have an important day ahead, I will just turn off my phone in the evening because I'm too scared of him rocking the boat and of being hurt.
How do I support him? Do I even support him, or does it sound like he would be better on his own? It's so hard to let go of someone I adore so much, and that's not even counting the lovely children, but it seems that the man I loved isn't here anymore.
