Because not every person is a sex obsessed liar. It is in human nature to he prone to temptation and technology makes it easy to indulge. It is on you to be savy and pick a person who is secure, who controls themselves, who has good insight into who he is and who has done a ton of personal growth to be an individual of good moral character not just because he is with you, but because of this is who he is.
When we serially get involved with troubled persons it seems like everyone is f----d up, but it is not true.
I have quite a few couple friends who has a little bit of problems, but were able to have long, successful marriages and remain committed to each other throughout.
Don't lose your faith in people, just have more faith in yourself that you are smarter, that you are worthy and do not settle for anything less.

Yes, as Aronia said.

You may not trust humans, and rightly so, because humans do let each other down, but it is important to trust in a higher power, that good will prevail if you put your faith and emotional energy in doing good yourself.

it may not be believable, but i've been married to my husband for 14 yrs. ours is a relationship that allows for either of us to have other relationships. the general populous tends to think the opposite, but it takes a TON of trust in my husband that he is going to stay with me and not flit off the many times he could have.

not all of us lie about who we are either. poly isn't for everyone. of course i still scratch my head at why so many cheat so much but i'm the odd one.

i might suggest instead of worrying about the rest of the world being trust worthy.. define very specifically what trust and trustworthiness is to you. then be upfront about it as well as focus on emulating that definition. i found when i did that, the ones that couldn't hack it fell away really fast and the ones who were in line with it found me and appreciate me because i am living my own standards. lies cannot stay in place of honesty.

thank you for reading my 2 cents. i hope it helped.

One thing is for sure: You CAN trust people to be selfish assholes. But you give a little bit...then wait to see if they give back. If they do, give a little more, and on it goes...if they stop giving, you stop giving too. Ebb and flow of give and take.

I like the "open, honest" approach to poly, Gypsy! If both of you are open that this is what you both want, and still make each other the priority, the "one to come home to", no one gets hurt, and I think this could work just fine.

My parents have been married for 51 yrs,
of course in the begining they had their ups/downs.
but they were commited to eachother.

3 weeks ago My mom died She died about a week or 2 after their 51 anniversary.

My 1st wife within 2 months of our marraige had sex with 2 other guys,
I forgave her, I actualy forgot about it.
She was very hard for us to live with , me & her HER 3 kids.
She was abusive to all of us, but I stayed with her until my last son (step) moved out, then I left her. I never cheated on her.
After I left her we had sex together with other ppl.
it was ploy to get me to come back to her, it didn't work.

For the past 10 + yrs I've been with my current wife,
we are faithful to eachother physicaly & mentaly.
There are ppl who don't cheat , if you don't dwell on it maybe you'll find 'the one' for you.
My wife & I found eachother when we weren't looking for someone .
