Buying a house

Okay so we are going to start looking into buying a house and looking around....How nervous am I!!!
Buying a house with someone is a HUGE commitment, not only to each other but also the house. We know what we want so that will make things easier and have agreed that if our relationship doesn't work out we will always be friends and can live together happily enough. I am not sure how that would work if we split up and brought in new relationships but as adults I am sure we could figure it out. We aren't unreasonable. Totally.
I just hope that our relationship works out the way we both want it to and that things go at least semi smoothly. I am very nervous about buying a house however for reasons other then the relationship. As anyone who has ever read my blog knows, I am a gypsy heart and soul, I like to travel and move around and enjoy new experiences. Can't do a lot of that if I make the commitment with Jim to purchase a home. I will need to be around to do the housely things and help pay bills and I am sure he would not appreciate it if I just took off and did my own gypsy thing for any amount of time over a week....Soooo scared and yet excited at the same time.
