It’s easy to get demotivated when you see how many men are awful!
FWIW my relationship has not been without it’s drama, but actually cheating isn’t high on my worry list.
For me, I’ve got to a place where I know I’d be fine without him, so I don’t worry about whether he may or may not cheat because if he did, well thats his loss! He’d be an idiot. And who wants to be with an idiot?!
We are both very loving and affectionate, build each other up and make each other feel special, so I don’t worry about him looking elsewhere because I’m confident in what he gets from me and that he wouldn’t get anything more elsewhere. I don’t mean being a “cool girl” and making it all about him, we give mutually.
Most affairs seem to happen, not because there’s necessarily something very wrong with the relationship, but because the other person makes them feel ‘seen’ and valued when their partner is distant or distracted (often for good reason).
If you make sure to both make each other feel seen and valued your relationship is less vulnerable to one of you cheating. And if you do get distracted by life then hopefully your relationship can weather the storm because you’ve banked up lots of love and trust.
I don’t think it’s exclusively men who cheat - I think often women may not physically cheat, but they do have their heads turned and compare their partner unfavourably to other men just as often.
I don’t consider myself a cheat. But when I was married to my ex I didn’t feel valued, he didn’t seem to want to spend time with me and our DCs, but I had a male friend who DID want to spend time with us, so I ended up with a big crush on him. Nothing happened but it has made me realise that even those of us who think cheating is awful can be swayed to fantasise about a better life with someone else when we feel invisible and it’s not a huge leap from that to actually cheating.
Esther Perel has some good TED talks about infidelity which might help you to work through some things. She gives an interesting insight into infidelity and how to rebuild afterwards. I’m sure a lot of that would be useful for you to hear before starting a new relationship.
