Well if you've been thinking about it for a year.........
Have you weighed up the pro's & cons - write them down. You need to ask yourself questions. How much have you talked to your DH about it , you need to talk with him and ask yourselves how it is going to affect your lives and your relationship , the sacrifices you both will have to make.
If you have done these things and you both still want to go ahead then it isn't an obsession.
DX : I'm me , suprisingly I've only just realised this.
