Two people don’t come up with the idea of an open relationship at the same
There is always one that wants it and the other person basically goes along with it

Its at best friends

I will also add
If the idea of seeing your partner have sex with another person turns you on then you are sick in the head

I would have to say no because I like to have peace in my life. It's not that I'm so delicate I couldn't cope with idea of being with someone with a checkered past, but at a point it's just common sense.

It's difficult to find people who truly believe in commitment now and can actually stick with it. So I would have trouble taking someone seriously, especially if marriage is even their goal, because harmony is very important and that requires both share values I think to make that feasible.

Also, a lot of people I've known to cheat or treat relationships too casually don't really have shame in that and so seem to have no problem justifying it. I actually respect someone for not waffling when it comes to being honest with themselves with their own limitations and I've learned a lot about life from such people. I just know it would be self-torture with the way my personality is because I can never treat relationships that casually.

And what would you say you’re looking for in a relationship? Is marriage always the end-sight (not saying that’s what you’re saying, but nonetheless man’s just curious, innit)?

It depends, like if they cheated when they were very young, I don't think it necessarily means they would always cheat in the future or couldn't ever change.

She is happily married and she has made it clear in her post how she views relationships and what’s with, man’s just curious innit, nonsense ?
Man’s just nosy more like

Relationships can fail at any stage and for many reasons, one or the other person can be to blame or a mixture of both

In general your new partner is always going to be someones ex , so you don’t get a brand new item it’s not going to be perfect

People also forgive those that have cheated on them so as they say
It’s complicated

I dont think its a black or white issue. Jeez, I wouldn't want to be tainted by mistakes I've made in the past. If there is honesty and openess in a relationship from the start, you can't ask for more. I would say there are worse traits a person can have than making a mistake in relationships past. You could miss out on the love of your life by judging them on something that could have happened years ago under circumstances you know nothing about.

Obviously if they are a player and have other red flags that would be different

I am married and have been with the same person for 20 years so that would probably answer your main question...

In general, I think of relationships as something that should never be treated in a trivial way or "wasted". That's true for friendships also. When someone takes the time to put their energy into you, it means something. Doubly so when it's intimate because it's a lot more energy involved than just hello/goodbye. Even if the person ends up being a giant dumpster fire, they've read into your life and contributed in some way into the understanding of your own heart and so also where you are heading. So I think of people who enter my life as people who play a part in my personal growth, so that kind of governs the types of connections I would seek. That said, my emotional track record with romantic connections was about the 6 month mark I would've gotten some kind of clue as to where it could go anywhere beyond that. So while that does color my long-term expectations quite a bit, it doesn't mean you can't have fun with that person or explore a connection. Anyway, I don't think marriage is something I could ever force from others.
