To wonder if he ever loved me?

[Notanotherpound]

I was with my ex for almost 20 years. It got to a point where he never prioritised me and the kids and was frequently going out with a group of friends from work. A month after our relationship ended I found out he has been introducing the kids to this other woman. Apparently nothing happened beforehand and he doesn’t want to be alone, am I being stupid to believe this?

I'm not sure I understand. Does he want to get back together?

I'm sorry OP but it sounds as though the relationship with her isn't a new one.
Probably when he was supposed to be with friends he was with her.

Why does it matter? Leave the past in the past.

When you realise you got bitten by a snake you don't chase after it to ask it why it bit you... you get some anti-venom and move on and try to avoid snakes in the future.

In this case you may want to get some counselling or lots of love from friends and family as your anti-venom.

I suppose it doesn't really matter now but if there ever was a simple way to tell, then I would say that if throughout your relationship you generally felt loved, then he probably did.

I would never ever go back now so yes I suppose my question is irrelevant

You seem to be asking two different questions here. In your post you ask whether you should believe that your ex wasn't having an affair with the woman he's now dating. In your title you ask whether he ever loved you. Those are two different things.

My guess is that he did meet his new partner before you split up (although that doesn't necessarily mean they actually started a relationship until after split).

However, that doesn't mean he 'never loved you'. It means he stopped loving you at some point in the relationship. It doesn't mean he never did. People can fall out of love.
