Let's Have a Break
I notice how, when I'm around you, you aren't your usual cheery self anymore. I don't think you need a person like me in your life right now. You really need to worry about the future, and it doesn't look like I'll be a part of it, and I just bring you down.
I still think our relationship can work if we both want it. I care for you very much.
Let's have a break. I'll call you next week.
