50NL HU - QQ C/F after 5B getting called?

Have been playing maybe 100 hands or so. His pretty tight and bad tho he is a winning player. I have raised BU 100% of the time and his been folding and open folding too much PF and not adjusting. His tilting a bit rite now due to couple of previous hands. I was hoping to get shoved over my 5B but was surprised by the flat. What do I do on this flop? Should I not have 5B and just shoved over his 4B pre?
