That depends on each individual relationship and what is okay or not okay in your relationship.
We really just don't do opposite sex friendships. I think in reality they're usually
My husband and I have a policy that the two of us are in the inside with eachother, all others are on the outside. No one gets in if either of us doesn't like it, that's automatic and that's it. Why let strangers come between you is how we see it.
Well, did you find out why she was training your husband? Perhaps she had a couple of guys she was working on and honing her trainer skills?
I can't blame your husband - if he was seeing results that's great. I also don't think that there's any great harm in him finding it titillating, even pleasant, to have a female trainer as long as that was the extent of his interest. Personally I'd find having a fit female trainer to be more motivating than a hairy sweat guy.
When your friend says you don't trust him or that you're insecure,
Michelabella, is your husband her ONLY workout buddy?
It's just that I have a male friend who is also very interested in personal training and he works out with and unofficially trains a small group of people who he works with. Male and female, married and unmarried. And he sees them at different times depending on who is at the gym when. The sex and marital status is unimportant...what is important is the willingness of the workout buddies to train.
I'd perhaps be concerned if your hubby was her only unofficial client, but if he's one of many then why do you not trust this situaton? Also, if he's the only one, is she working towards getting a few other workout buddies?
I will not comment on the issues of control or jealousy until I know more about the dynamics of her other workout buddies
