Opinion....Did he Cheat?

Wait on callling. Talk to your husband, as CALMLY as you can one more time. Something sounds fishy and I'm only saying this because there are some catty women out there who do things like this to cause trouble. Think if you can think of anyone who may not like you? Or a woman he works with that may have a crush and is trying to cause trouble...I don't think it's odd that she knows your name, in this day and age information is easily accessible. This also sounds like it may have been someone young? Especially with the content of the second call.....you have to sit down with him again. Tell him you have this woman/girl's phone number, and how much this is eating you up. If he tries to stop you, then I would definitely be a little suspicious. If he tells you to feel free to find out - do just that. Feel free to email me - I've been through a similar situation.
