Maybe ask for something other than a raise, more holiday days, lower regular expected weekly hours. Argue with your experience and look for something he can make happen, if they cant support a higher wage. If overtime hours are not yet being paid out or used up as holidays ask for this as well... you like the position, you like the team, and you dont really want to change job , thats fine so go for something that is worth it for you outside of more money.
If they are not willing to adjust anything, they dont really value you enough, then you at least know it and can start looking for something else.
