My mom is nitpicking everything.. Suggestions appreciated

"Mom, I know you're trying to be helpful, but when you say things like that, I find it hurtful, as it feels very critical."

And if that doesn't work, "Thanks for your thoughts" and change the subject.

Just talk to her. My mom asked like that until I let her know I'm under enough stress, and I need her to be supportive. "Instead of telling me what is wrong with my idea tell me how to better my idea"

Thanks @BookcaseHat I'll try the second one. Hopefully she can get the hint eventually.

What I would do, especially if she can't get the hint, is don't talk about any wedding plans with her. Sorry, Mom, I can't tell you -it's going to be a surprise!

I would say something along the lines of "mom, i understand you think that way and I appreciate your opinion, but your hurting my feelings, these are things i want for my wedding and its bumming me to hear you critique everything" basically what @BookcaseHat said just worded differently

Yeah @Devon I haven't been including her for the reason that she is very negative and don't think it will be fun to collaborate with her. I will try to let her know it's hurting my feelings next time though. Thanks you guys

Don't talk about it around her anymore. If she gives suggestions just say thanks I'll think about it. Then do what you want. I had to do that all

Of my life with my parents.

Seem like we are in the same boat. I just started ignoring my mom negative talk because I won't let her drive me crazy. If your like me and don't wanna hurt her feelings I would say ignore her even though being passive isn't going to solve any problems for the future.
