Hi Laurie ~ If this change has come about rather sudden, I would wonder too!
Does his job take him out of town, or did he just leave? Didn't he tell you where he was going?
You have a RIGHT to know where he has been and WHAT he has been doing. Ask him if the role was reversed, what would happen? If YOU had been gone 4 days, and didn't say anything, what would happen? Wouldn't HE be upset? Wouldn't HE wonder what was going on? Wouldn't HE be hurt and confused? And what about sex? If YOU didn't want sex anymore, what would HE think?
If you turn everything around, perhaps he'll understand why YOU are so upset!
I wouldn't put up with this -- it sounds to me like he has someone else! Of course you would have to have some proof. Can you get into his cell phone and find out?
It's up to you to find out what's going on. Try to communicate without fighting. Keep urging him to talk to you -- he can't keep silent forever. Ask him to go to marriage counseling with you -- otherwise this marriage may be doomed. God bless and please take care. Hugs, Lee
