Is this cheating?

[JoySomber]

Name changed

Me and my DH have been together for almost 7 years married for 4. And we have 2 boys 5 and 2 and a 5 month old girl

I caught DH messaging his friend saying if He was single he would date her. I confronted him and he said he would but he isn't single so he wouldn't do anything with her.

Now last night my eldest was playing on his phone and messages popped up with his friend and I looked through some of the texts and a few weeks ago DH was asking if she wanted to go for a drink with him.

And then on Sunday he said really enjoyed yesterday xx.

I mentioned it to him and asked why I was spying on his messages when I wasn't

Is this cheating? What can I do?

Cheating or not, he is being completely disrespectful to you by telling someone else he would be with her "if it wasn't for you". I suppose ir depends on where your boundaries lie but I reckon his behaviour would be over the line for most people
