Does my husband have to pay any alimony in california if i file for divorce?

After being together for 3 years, We got married in Feb 2014 and as soon as he moved in with me and the kids, he said he was going to leave us because he can't "handle the responsibility" of kids and a wife. He said his ex wife and ex stepson are his only "real family". He then said in April that he was going to seek counseling because he drove to a store to purchase a gun and was going to commit suicide. I was shocked and it's been a roller coaster with him emotionally . He kept saying "when he leaves" he will give me enough money to help with our rent for 6 months or $20000. I can't afford the full rent on my own. a couple of weeks ago, I saw that he wrote an email to his ex-wife stating he'll never love anyone as much as her and that without her in his life, he will commit suicide by his next birthday. Clearly, I was alarmed and told him to get out of the house. (what I meant was right then- for an hour) but he says I "kicked him out" so he doesn't have to keep his word to hep with
