I posted on here a while back about my husband leaving & his behaviour. Most people who commented on the thread said he absolutely had another woman. Turns out everyone was correct, although they are maintaining they got together after we separated! However, they were seen on numerous occasions meeting together when he was still in the family home. He had been leaving for 'work' early only to be actually meeting her in a car park 
Now they are openly parading their romance. He is currently abroad with her, having lied to our DD that he was going away for a couple of days by himself!! How do I shake this constant sinking feeling of dread 😟
