Cheating Husband??

I have just found some Facebook messages on my husbands phone with another woman.

It looks as though some messages have been deleted.

The messages I could see was him apologising for not messaging back and that he was at work. He had just sent another 2 messages saying he'd fell asleep and just woke up.

I don't believe he has met up with this girl but I think he met her on his works Christmas party. I know he wouldn't have met up with her because he goes to work and comes straight home and were always together on the weekends.

I have questioned him about it and he says he used to work with her and I've asked why he's apologising to her and he cannot give me a straight answer!

He's only been friends with her on Facebook for a few weeks.

We been together 5 years and married for 3 and have a 2 year old daughter and a 6 week old son and I'm absolutely gutted.

He's sitting on the sofa playing his video games like nothing has happened and I'm absolutely fuming!

Does it sound like he was lining up this women to get ready to cheat on me, or am I seeing too much into this?

What do I do?
