I Feel So Depressed.. I Don't Know What To Do.

I have been dating the most amazing man, that I have ever met for almost 6 months. I can be emotional, or silly, or sad or happy or anything, I can be me, and he accepts me for me. He loves me, but lately we have been having a small rough patch, and we get extra emotional or sad and end up in small arguments or bad ngihts over the smallest things, a lot of the time it is me because I get upset over something small. But anyways...

I feel like maybe he would be happier without me. I have three kids, I don't work, I go to school full time but even once I graduate I am going to be in debt from school loans. I can't afford to move financially or help pay rent. My kids can be stressful at times I have three from a previous relationship. And I just feel like I am a huge burden.. He never said any of this.. but thinking ahead I have nothing to offer him but my love. and.. sometimes love isn't enough. The most I will be offering is more stress and baggage and just a big burden on him and I feel like I will just be holding him back. 

I don't know what to do. I love him so much. :(
