When they decided to have a baby Luke made a commitment

I'm a little annoyed at how Luke and Prue were acting last episode. It's not Lizzie vs Prue. It's not. When Luke chose to have a baby with Lizzie he made a commitment to be around and jumping off of a cliff because your new wife is jealous of your lesbian best friend is a little f-ed up. I also don't understand why Prue had to take over their one day. If you know Sunday is their day for the Farmer's Market, which they both clearly enjoy, why did she tag along just to complain and then try to make him leave? If she didn't want to go she didn't have to, and it's not fair to try to force him to leave something he clearly enjoys just because you want to do something else. Go do it. No one is stopping you. Why not have Saturday be their "thrill" day and let Sunday be Farmer's Market day?

I have literally never posted any persona comments like this on IMDB but I was just very annoyed by this whole thing. Honestly, if this show continues on being what it is, 30 year olds acting like teenagers when they are real issues they could be exploring, I'm probably going to stop watching pretty soon.
