Help with moh please!

The best thing is to just ask her. It is as simple as sending her a message (this won't put her on the spot as much as it will asking her in a telephone call) to the following effect:

"Hey [name]

I would love to have you as my maid of honour but I am not sure if this is too great of an ask of you since we are on opposite sides of the country.

Anyway, I wanted to give you the option to think about it - let me know how you feel about it once you have had some time to think it over".

With this said, I would highly suggest not asking anyone to be in your bridal party until closer to the wedding - your wedding is almost 2 years away and your friendships and circumstances may change much more than you think in that time.

Exactly what PP said! ^^

You also need to see what your expectations of her are. A lot of times brides become disappointed and feel let down because none of their bridesmaids lived up to their "expectations". Here's the problem with that. At the end of the day, a bridesmaid's main role is to show up and stand by the bride's side to say "I do." If they are super helpful with all the wedding planning and what not then that is just a bonus.

Brides tend to assume that their bridesmaids understand the "task" of a bridesmaid when it wasn't clear within that CIRCLE. Some bridesmaids won't probably do anything because it wasn't communicated in the first place because of the assumption of the bride. Also, some brides assume that their girls will be there at all the wedding activities and festivities, will help with this and that, etc. In reality, they may not be able to live up to those tasks and expectations when they have other priorities, jobs, school, finances, families, etc. So, these are just some things to consider if you want her to be a MOH
