Someone mentioned my husband should get a better paying job. Well, he has applied to several different ones in the past 2 months and none has yet to reply.
Keep applying. It takes exactly one person to say yes.
Look, the poverty guidelines aren't exactly onerous. $17,200 a year translates to around $8/hour, which isn't much more than minimum wage. If someone came to me wanting to marry one of
my daughters who couldn't even manage this much, I'd tell him he was trespassing and not to try such a stunt again.
Snide comments aside, his lack of income is an ominous sign for your marriage and you need to work together with your husband to ensure that the two of you become independent adults. And while love is so much more than money, financial independence is a key part of adulthood. What is your husband's education? His skills? Why can't he get a job paying $8/hour? Can he a get a second, part-time job?
I don't mean to say this to beat you (or him) up, but the income situation needs to be resolved, and hitting someone up for the affadavit of support or a gift of a substantial amount is not going to resolve the situation. Your marriage depends on it.
he's working in the same place as his step-dad and no one there can do his position without extensive training first
If that is the case, then there is no way that someone holding such a position could not make more than $8.25/hour. Sorry, I don't believe it. One of two things is true - either the position requires no special skills, or he is being woefully underpaid. Which of the two is the case I cannot tell you, but it is one or the other.
I will point out that I would be a woeful failure as a father if I was to hold my children back in a poverty-wage job to the extent that their marriage failed, even if the job is specialized. So his stepdad needs to be a man and a father and let him move forward, and your husband needs to be a man and get in a situation where he can adequately support his family.
