<human>: My husband and I have been married for three years now. I really love him, which makes this situation all the more frustrating. I feel like he's not living up to his potential.

Since we've gotten married, he's only held one job for more than six months, and goes months at a time with no job at all, relying on me to support him. I just graduated with my bachelor's and am now pursuing my master's, so funds are tight enough as they are without him being unable to pull his weight. He's been in college for four years now, and is still at least two away from graduating with a bachelor's because he keeps failing classes and needing to retake them. I know he's not unintelligent, he just seems like he can't apply himself to getting good grades. It's becoming a real problem, because each time he retakes a class it just adds to our student loan debt, which he also can't seem to express any concern over. 

I'm exhausted, trying to be competitive in my master's program while also trying to pay the bills with no help from him. I'm tired of being a sugar momma. I have no idea how he plans to support our family in the future if he can't hold down a job or get a degree. I wouldn't mind even if he dropped college in favor of doing a trade, just so long as it's something that pays the bills!

Just so you know, I have told him exactly how I feel, several times. We've had mature, civilized discussions about how to improve the situation, and he always ends it by telling me he'll do better in the future. I know this sort of change takes a lot of time and effort, so I try really hard not to ride him or nag him about it. I'm just getting tired and frustrated, and I'd like some advice about what I can do to make the situation better. Even advice about how to better handle my frustration and keep it from growing into resentment would be deeply appreciated.

<bot>: I'm my husband's sugar momma, and I don't like it. How can I change the situation, or better deal with my resentment?
