Hi Heather-
I just finished potty training my little one, too, so I understand your frustration.
Unfortunately, until he's interested in it (and he will be, don't worry!), he won't really truly be ready to potty train completely. A friend of mine (preschool teacher) said a lot of boys aren't really ready for it until they're nearly 4 years old!
With my daughter, we put a little potty chair in the living room so she could sit on it while watching TV. We praised any and all efforts (even when she was just hanging out on there) when she "used" the potty. Eventually, she started wanting to go sit on it even when she didn't need to actually go, but we praised her just the same. That way, the potty was always a good thing. We also have never made a big deal out of accidents. Kids use the bathroom as a control thing if they know it bothers you. And of course, every time she actually peed in it, we were super excited for her and told her how proud we were of her. Even now, we let her know. In all, I think potty training took us about 3-4 months before she was in panties all day (still a diaper at night, she doesn't wake up when she has to go yet), even out of the house. We tried potty training a couple times, but it wasn't until she decided she was ready (showing interest by herself in using the toilet) that things really took off.
Good luck!
T.
