"life as it happens"

my brother Kyle is getting married and im in the wedding which im very honored to be asked. however it also brings up the fact that we are so close and i rely on him for allot... but since him and Tricia (future sister in law) has moved in together things have changed and i am trying to adapt to them its just im afraid that once they are married and his life with Tricia is in full swing that our talks that we have and our relationship will suffer... or at least be allot different im just really nervous bc this week has been really hard and he hasn't been around for a while..... i guess what im saying is i wish that somethings wouldn't change
