Is he cheating?

Okkk the warning bells are going off like crazy. There is def something up even if he hasn't actually cheated more than likely he's cheated in his heart. So I mean if you want to give him a chance to come clean then do so but be very careful once a cheater usually always a cheater

As someone said, you know him best follow your instinct. It really sounds like if he is not cheating on you. It sure seems like he has put some thought into it.

I would definitely confront him about it, and tell him how you feel. His behavoir is very suspicious, to say the least! If he is not cheating on you, it sure seems like he is. He needs to stop this behavoir, or your marriage is in trouble. I would not let him get away with acting this way with another woman.

I think he's cheating on you. when guys hiding something from you, its a red light that he might be up to something that will hurt you. and especially he always said he didn't remember or he didn't know when you asked him about all this. and when guys make a offense attitude when you asking the same topics, it means that he really hiding something from you, and you must trust your instinct that something is really going on.

He makes the schedule? How convenient. There are too many signs pointing in a negative direction then positive. I guarantee if you shared the same relationship with a member of the opposite sex, your husband would not like that connection. If he was 100% about you, it should be in his best interest to make your schedule and his coincide so that you all could spend time together versus you working late and him getting off early. Way too coincidental. Marriage is an important commitment and without full "in the action" proof, there are plenty of ways where situations can be manipulated. Regardless of what is being said, it is unlogical for your husband to just flat out say "OKAY, you caught me, I'm cheating!" LOL. If your intuition will not leave you alone, I would hire a private detective. Pretty expensive, but well worth it. This IS your marriage, your heart on the line, your feelings, and livelihood. I think it would be worthwhile to find out now and be heartbroken, then to find out later when its waaay too late, and then end up being on Oxygen's SNAPPED. I wish you the best of luck! Also, when confronting the situation, be prepared for an even sneakier approach, which is what he will take on once he knows that you are "on to him".

His behavior is questionable and inappropriate. I was married before so I can talk about this. Tell him straight up, with no sugar coating how his erratic behavior makes you feel. Be cautious of this woman, you have other friends.

Talk with him and ask him to put the shoe on the other foot. He would flip if you did all those things he did. His behavior with his co-worker could lead to other forms of cheating. Communicate, communicate, communicate.
