It has been four years since Showtime premiered Weeds, a witty little dramedy about a widowed suburban mom who turns to drug dealing in order to support her family's comfortable lifestyle. But even after 53 episodes, two towns and numerous romantic liasons, Nancy Botwin, played by the doe-eyed Mary Louise Parker, doesn't seem to have improved her decision-making skills. Same goes for the rest of the Botwin clan and their friends. But, everyone's blunders have made for great TV. In honor of the recent premiere of the 5th season, here are three things we've learned about love from watching Weeds.

1. Don't stay with him for the so-called security.

In season two, Nancy got involved with a single dad named Peter—who turned out to be a DEA agent. The two secretly married in order to prevent his having to testify against her. But despite Peter's all-around good intentions and genuine feelings (I mean, after all, the man did clear away an entire neighborhood of competition for her), Nancy never felt the same way back. But rather than cutting it off like any normal couple would, she went along with the charade until it backfired. One jilted DEA agent makes for one helluva hairy situation, so make that a parable for all of us: If you're not feeling the love, it's pointless to keep the act going. Someone will get hurt far worse than you think. Watch: When It's OK To Lie To Your Boyfriend 

2. A man manages his work like he manages his love life.

Nancy's steamy tryst with corrupt Tijuana mayor, Esteban, in season four was muy caliente. But who can truly believe this affair is going anywhere but downhill? Esteban doesn't only traffic drugs but humans as well. He's a prime cut from the cloth of chauvinism and it only takes one look at the way he manages his cutthroat business to see that. Leave it to Mrs. Botwin to fall for the most complex villain on the show. A good way to see how a man will react to relationship problems is to look at how he manages problems in his day-to-day life. As an extreme example, someone who doesn't mind smuggling women into prostitution might not be the gentle, considerate mate you're looking for. Read: Relationships Are Like Politics
