My flatmate who is also my best friend is getting married. Before the wedding preparation became public notice (officially announced to all), she use to go on and on to me about how she wants her wedding to go. But eventually, the whole wedding plan has taken a different turn contrary to her initial plans. Seems she is easily influenced by peoples opinion(Aunts, sisters etc) as against hers E.G. she comes home and she has bought the same thing she told me she wouldn't buy... when I ask why she says because AuntyA said so etc sometimes she doesn't even bother telling me when she goes off the plan (maybe because I might shrug... "I thought you said u didn't want...ok"). This sort of irritates me, sometimes I just want to sit her down and give a 24-hour-lecture on being strong-willed and doing HER thing. She also doesn't take unfavorable judgments well (you'll see it in her eyes)
I have a critical mind (but sometimes I might never say anything)
Please how do I (generally) not be too critical, shut-up, smile and just go along with her plan(even when I don't agree)? Or what do you advice a best friend to do in this kind of situation?

And please if I have my own place and my wedding venue is closer to my apartment, would it be disrespectful to my parents if I don't go dress-up at theirs' and leave from theirs' for my wedding? (generally)

Thanks y'all

When your roommate comes home and talks about her wedding, you could ask her in a friendly but not challenging or judging manner, "how are you feeling about everything - are you enjoying the process of planning the wedding?" If she seems on the fence you could just ask, "I can't help but notice you're trying very hard to please everyone --I just wanted to ask to make sure that your dreams are being realized, too". Then it's up to her whether she wants to talk about it but if you pressure her, it's just one more person finding fault with how she's managing, so I wouldn't do that.

As for your own plans, if your parents have dreams of taking pictures at the house and leaving there with you to go to church so their neighbors all see their beautiful daughter, it's a small thing to do for the people who raised you - the convenience of being closer to the venue isn't a worthwhile tradeoff unless it's like an hour or more closer in my opinion. If you expect horrible traffic or weather, it's a different story and you might suggest that everyone stay close to the venue.

I really appreciate your response, it sure was helpful, I'll keep it cool (I've not really been pressuring though)
And my second question was just a general one on if parents will feel disrespected if their marrying-kids don't leave from theirs.

Thanks again
