this is my second post so i am by no means an expert. sounds like you and hubby need to have some serious talks about ground rules.
1)are you ok with hubby having his own girlfriend as long as he does not neglect you are tell you about their advertures?
2)are you capable of have 2 seperate relationships and not neglect one or the other?
3)are there any trust issues between you and hubby that have not been resolved that can complicate this further?
