1. YOUR WORK SPOUSE
It's perfectly fine to have a guy friend you get along with well. However, you don't want to get too close to him. If you do, then your boyfriend is going to get jealous of all of the time you're spending together. Just be careful not to cross any lines.
2. YOUR MOTHER-IN-LAW
Your mother-in-law probably means well, but she shouldn't be interfering in your relationship. If she's always lecturing you on the right way to cook and clean, you're eventually going to snap at her. She should trust your judgement, and she shouldn't be trying to compete with you for your man's affection. If she does, then it's only going to cause issues.
3. YOUR GUY'S FEMALE BFF
There's nothing wrong with having a friend of the opposite sex. Of course, if your man spends more time with his female best friend than he does with you, it'll make you wonder why they aren't the ones dating. That jealousy can ruin your relationship, so watch out.
4. YOUR PERSONAL TRAINER
If your trainer is a hot, muscled man, then it makes sense for your own man to be jealous. After all, it's easy to fall for someone at the gym when you're looking at half naked strangers while filled with adrenaline. Of course, your man needs to learn to trust you, even when you're around hot guys.
5. YOUR THERAPIST
Your man might be worried about how much you're telling your therapist about him. He'll hope that you aren't ranting about how horrible your relationship is. To calm his fears, you might want to mention what you talked about during the session as soon as you get home.
6. YOUR FURRY FRIEND
Believe it or not, plenty of people will get jealous of their partner's pets. Why? Because they get all of the affection!
