Remember that the owner only pays you for the time you're at the job. So if you work six more months and leave, he only paid you for six months of work at the new salary. And you did six months of work. It's not like you're asking for a five year bonus, and then leave in six months.

Don't feel ashamed to ask the owner for a raise if you feel like you deserve one. Change your perspective. They should be ashamed that they haven't been trying to do their best by you. And if it does come down to hurting feelings... who do you care more about, the owner or your wife and kids?
