Ridiculous Relationship

I've been watching "The Glades" on Amazon and was just wondering if anyone else found the relationship woes between Jim and Callie ridiculous? They sleep together, then Ray comes back, but Jim's still interested and clearly jealous. Then his old partner (who treated him like crap, not telling him she was engaged) comes back, and this is where it gets just silly. Jim keeps telling Callie that's he's not interested in Sam, then turns around and keeps telling Sam that there's nothing between him and Callie because she's still married. This goes on for a few episodes, with Jim acting increasingly cold toward Callie while hanging out with Sam all the time, but still telling Callie that he's not interested in Sam. Then suddenly Sam heads back to Chicago and in the very next episode, Jim's back to trying to get Callie to hang out again, buying her pizza, asking her to look at his snakebite, etc. Are we honestly supposed to believe that a strong, intelligent woman like Callie would put up with this? He basically blew her off when there was another woman around and now that he's alone again, he expects to pick up where they left off. It's pretty bad writing, which is a shame, because the show was pretty good. If the writers needed a way to keep the characters apart for a while to prolong the suspense of the romance, they could have come up with something that didn't make Jim look like such an a-hole and Callie such a wimp.
