I’ve ghosted him, am I right to do so?

Have been seeing a guy at work for six months. He’s separated and has been for a while, his wife had an affair with an ex.
He was saying all the right things, I’ve fancied him for ages and really really fancy him. We get along amazingly and I was so happy with him.
I asked him to do something nice at the weekend, he told me he had his kids and will have his kids most weekends now. Fine, not a problem.
My friend seen him with his wife at a restaurant on Saturday night. He lied to me. For the first few days I didn’t let on that I knew, wanted to see if he would tell me. He brazingly carried on as normal, chatting with me at work and looking at me all lustfully.

I started to avoid him at work, just so I wouldn’t have to see his face. He’s picked up on these hints and hasn’t asked me what’s wrong. I was stood right next to him today and I completely ignored him. I’ve blocked his number and social media. I assume he knows why.
I just feel terrible because if I was a guy that done that to a woman it would be emotionally abusive. Should I tell him why or just carry on moving forward?

Me and my ex husband used to do the occasional thing together with the children. We figured it was healthy for them to see us being amicable. It didn't work in our case, but are you absolutely certain it's not something like that? Some separated couples are able to maintain civility and continue to do stuff together with the kids ... not sustainable in our case sadly, but we did start off with good intentions

But he wasn't with the kids, just his ex. And yet, he was telling OP he was having the DC that weekend, no mention of his ex. OP says she's caught him out in liess previously, so sadly I think it's a case of a bloke happy to lie to get what he wants.

Something similar happened to me a few weeks ago, was dating a guy, all going good then a few things didn't add up and I worked out he was still living with his wife, I didn't tell him I k ew straight away, I gave him several opertunities to tell me by asking questions. Eventually I just asked him outright and he gave me a load of ball shot about how he can't afford his own place and how he needed support for his mental health. I then just stopped replying. Seems a lot of guys think they can get aways with this, this wasn't the first I had dated that ended up still being with his wife/partner.
