I had to shake my head and chuckle over your "mail". I'm glad you got your key back...but that doesn't mean he didn't make a copy. Continue to deadbolt your door when you aren't home. Now, if your MIL will give you her key, you'll be good to go. After all, it is your home for the time being and you certainly don't want someone just walking in unannounced.
As for travel groups, I've used them quite often and have found them a lot of fun and you do meet a lot of new people. I've stayed in touch w/some "new" friends for over 15 years and have visited them in their areas and vice versa. I recommend them, especially if you are traveling alone in a foreign country.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
