I really don't know how to respond to this in a positive way , but IF she really needs time away OK , but changing lock and not wanting to see / hear from you at all ? 7 weeks?? I'm not sure how you can even stay away for 2+ week if your really in love , I've only been married 3 years as of this week, We tend to fight now and then but nothing big , BUT in no way could we ever go off without each other for 2 weeks . A few months ago I went off to Texas for work and I was so upset about leaving her I almost turned around 5 different times.
I hope the best works out for you, but I'm not seeing changing the locks and not even wanting to talk to you like a positive thing. If she's trying to take a break then why go off parting with these other guy�s? I'm not sure I rally call that taking a break

I know when / IF my wife gets mad at me I just leave her alone and take the dogs for a long walk , I come back and say I'm sorry or something of the nature and its fine and dandy .
OH and changing the phone number too? Hmmmmmmmm, OK not seeing you and changing the locks ...well OK but NO communication isn't good man ...no good at all.
