I have a friend who is also engaged. I want to ask her to be one of my bridesmaids but her wedding is set for October 2016 and mine is June 2016. I feel like I would be encrouching on her "bride time" and that's the last thing that I want to do. I also don't want her to feel like I am leaving her out.
Re: Should I ask her to be a bridesmaid?
Forget the fact that she's getting married. Do you want her as one of your bridesmaids? That's the only thing that matters.
We went to our cousin's shower/bachelorette two months before my sister (C) got married. Then, C was MC at cousin's wedding a month and a half before her own wedding. I was C's MOH two months before I got married, and she was my MOH. None of that encroached on anything/anyone else. Why on earth would it?
Both of you have over a year until your wedding - even if you're only half organized, you can get things done at a nice, leisurely pace and not be stressed about it. We planned our wedding in four months, and the only thing I was stressed over was the one thing I didn't have control over (weather - my grandma said she wasn't coming if there was snow on the ground). And ditto what Esstee said - the person you should be venting to is the other person getting married at YOUR wedding.
ETA - my sister and I both had moments where we would text each other and say 'such and such wedding planning, grr, argh', and the other would commiserate because they were going through the same thing - but it didn't add to the other person's stress level. Why would it? It was the other person's wedding.
