My question wouldn’t be: what shall I do if he’s having another affair? It would be: why do I still want to be with a man who’s ostracised my kids, cheated several times and talks to me like I’m nothing?

You, on the other hand, sound like a fantastic woman and the relationship with your grandson sounds wonderful – he’s your life.

So my next question would be: how can I get out of this marriage? Please don’t stay with him because it’s been years. But if you want to be with him forever and are terrified he’s having an affair or wants one, then you have to be up front with him about how you feel.

Trouble is, if he is up to something, he probably assumes he can do it again as you forgave him the other affairs. He has no boundaries and if he thinks he can act how he likes with no consequences, he’s unlikely to change. I hope you find the strength to walk away – I know you deserve a lot better, even if you don’t entirely believe it.
