How do I tell my husband I need a little vacation without hurting his feelings?

My home life has really, really been stressing me out lately. I have an opportunity to go see my best girlfriend, and work has already approved the time off. We can’t really afford it, but I know I can sell some of my things to get the ticket. I feel like I really need this, and to be honest I feel like I deserve it. I know if I tell this to my husband he will be hurt and will try to make me feel bad for going – how do I navigate this? I am so tired I can’t really think straight right now, any advice?
