Don't forget that all those who are saying don't do it started out wanting to do nothing else. If an aviation career is calling you and you can't get the song out of your head then go for it. My wife was very supportive when I started out and still is but I would not want to push things and unilaterally decide that I am now off to the Middle East or freighters out of the US. Spousal patience does have its limits but if she is agreeable now then hold hands and jump in together.
