My husband is the sweetest guy I know. He gets along with everyone and is very compassionate. He has this friend from work whom he texts with almost everyday, whether she initiates or not. They've gone out to lunch/dinner together a few times and she comes to our house with a group of people from work to hang out. They call each other "sister from another mister" and "brother from another mother". She's asked me to hang out a few times, which I've tried to get to know her and gone out but there's something in me that won't let me trust her. I've seen their text messages and there's nothing inappropriate in them. She mostly talks to my husband about men in her life. However, they haven't even known eachother for a year, which seems weird to me how close they act like they are. I've told my husband that I'm not 100% comfortable with the friendship but I don't think he took me that seriously. In the past, he voiced his concerns about a work friend of mine who would text with me frequently. I stopped texting with him afterward unless it was about work. This girl has tried to get close to me but, again, there's something in me that won't trust her.
