Need a guy's opinion ....?

Perhaps he's grown up and realises that you were not just a lover back then but also a friend ,and now he wants you as a friend again? On the other hand he could be making a subtle move to win you back ,even though he shows now signs at the moment. Whichever one this is dangerous ground for you as your in a settled relationship with what sounds like a very understanding fella. Only you can make the right decision for you and the men in your life
