TRUST YOUR GUT:bangbang:
I did! And good thing I did because I found out they did mess around!! 
Trust your gut…always…
Always trust your gut
I say trust your instincts
Always trust you gutt
Always trust your gut.
Yes cut her off!!!
Trust your gut. Ask her
listen to your gut feeling and get rid of her
Trust your gut and ask her outright
Hmmm, trust your gut.
Talk to your husband
TRUST your instincts
You ask your husband. Clear your concious.
Trust your instincts.
Once you “catch them doing something”, it’s already too late. Cut her off immediately. You’ve been without your husband before as he’s travelled. You’ll be fine!
Sounds like there’s “something” there, but could it be a friendship or innocent flirtation? What is your relationship with your husband? Do you crack jokes with him? If you don’t feel comfortable talking to him, this could be an issue. Do you fear the response he may give you?
My personal experience…don’t trust either of them. I never thought my husband would do what he did…on my birthday. With my I thought was my bestfriend. Been divorced for a year now. Never did forgive him for it. And I knew it would happen. I felt it.
Instinct all the way, I had a friend like that. She was like a sister… month after me and my bf of 4 years broke up she was sleeping with him after watching everything we went threw together and she stayed with us , practically lived with us and they “didn’t like each other” & she claimed she hated him for how he treated me and my son but kept peace with him for the sake of mine and her friendship. Safe to say I don’t think she hated him 
When you catch them staring at each other - ask what’s the deal? She how they react???
Quit flipping out, you are obviously very insecure and thats on you. Maybe go gets some help if your depressed and insecure.
Trust your gut! Don’t open your doors to any female, the devil is real!
Dont forget he has a part in this also, if not more…
Honey trust your instinct. Cut her off. Talking from experience.
Unless you’re naturally jealous you may be feeling something is of subconsciously
One, I would always say, always always always go with your gut feeling. … like, always. A woman’s intuition is a gift from god to let you know when your being a naïeve bitch lol … no, but seriously, it really is.
But also, I would be an adult and openly have the conversation with both of them at the same time, and let them know what’s bothering you.
Make them squirm for a few, watch the reactions and watch the body language. That will give you a gauge on what’s actually going down.
But again
Trust your gut !
