I am struggling in my relationship with my boyfriend, Jim.

While I am beyond grateful that he FINALLY has a job and is happy to be working, his confidence level is getting to where he's coming off as a bit of a jerk. I can't help but feel underappreciated; and our communication problems are becoming obvious. I feel like I'm the only one who wants to work on this, while he seems content to let it all fall down around our ears!
I'm not happy, and since I'm new to the whole relationship process, I guess I'm asking for guidance.

I don't know what to say or do without offending him or putting him on his guard.
I feel like such a failure.
Please help me, God!
