It's been almost a week, should I worry about him being in touch?

Sorry honey, I know it's not what you wanted to hear but you must learn to respect yourself more and not allow yourself to be "taken for a ride"! There is a true story in the Daily Mail of a woman, married for 21 years, who has just found that her husband has relationships with women in various parts of the world and has even married one, so committing bigamy. Do the sensible thing, be strong and FORGET HIM - you owe it to yourself. Good luck. God bless. Gladgran.
