Am I over-reacting? Has anyone been here before?

Tell her how you feel, I would...And that is gonna cause problems cause most likely she is gonna be jealous and pout to him about it, and try the "we have been friends longer than you have been with her" and Ive always been there for you crap...and lay one hell of a guilt trip on him...but he is your man and you should come first...I would just lay it down to him, Lord knows if it had been my man hugging her and her face touching his....Her face would have been touching the cold hard floor!!! Don't let her run over you, usually the nice ones are the ones who will stab you in the back the quickest...trust me I know, I have been in your shoe's before...and I caught my Boyfriend/now husband kissing his so called best friend...I laid her out and busted his nose!!! but we had a long long talk about it and he never talked to her again...Loose women like that are fun to hang with and have flings with but when they want a real woman they always run back home...and most likely if they are that close, there has been intimacy, My husband swore up and down he had never touched his friend, but after I caught them, he came clean with it, told me all about how they partied and would get drunk and end up sleeping together...So I would put the smack down on the I love you, I miss you crap, and if that doesn't work...turn the tables on him...call a guy friend of yours up, and start my spacing and talking on the phone and having drinks and see how he feels about that...Don't take it!!!
