My wife keeps lying to me...?

She keeps lying to me about texting and talking to a mutual guy friend of ours. She isn't cheating and I know that for a fact but this guy is recently divorced so I am kinda wary of her talking to him. Also I'm not to good with trust in the first place but now that I've been fed a constant stream of lies I am even more paranoid. I'm not jealous at all I realize that she is with ME and she wouldn't be if she didn't actually want too. I love her and I know she loves me but she says I need to loosen up a little bit. Watcha think?
