D.P.
On September 4th (just 18 days ago) you wrote this about your husband: "I do still love him and i couldnt imagine going a day without him" What the heck is going on?
You are both very young. IMO, I think you owe it to each other and to your daughter to try marriage counseling before you start thinking about things like moving back near your family, your hubby dating others, etc.
Think of it this way--it couldn't hurt and to me, you seem confused and unsure. Sometimes the best thing to do when you're emotional, upset, confused and unsure is...nothing. Please think about counseling.
