why won't he take me on a date ????

Raven
We've been together for 3 years. And still have yet to go out on an actual date. We both work part time jobs so money is tight but why can't a little money every now and then be put aside so we can go out ? Is he ashamed of me ? Am I doing something wrong ? His only excuse is money and I told him that we can go somewhere cheap or even just walk around but I feel like he doesn't want to be seen with me. I've told him how I've felt multiple times and it's always the same lame excuse. What do I do ? Please help :( I'm getting very emotional about this
