When you ask a question on this site, anyone can answer. Being an expert in pets, doesn't mean I have no clue about relationships, or people. The fact that you became so angry about what I said, speaks volumes. I must have hit the nail on the head.

I say, go with your gut. The guy sounds like a creep. You've been with him a while. It might be time to rethink your future with him or tell him you will not do what he suggest and don't bring it up to you again. If he does, leave him. I think he might have desires to do this himself for the money an you're the next best thing.

Attitude aside a woman with self respect, which OP states she has, wouldn't be asking the question.

No matter what his reason the fiancé (of 7 years) is a loser - and still the fiancé - ?
