For men, this is how they see it. But women, it's different. A woman may claim that's all she wants... but that's normally not true.
Many times I've seen it where the woman says she's completely happy with the commitment-less relationship... but then they are miserable.
There's a girl (I'll call her Tammy since she didn't give me permission to share this), and she had exactly this kind of relationship. Tammy hung out with this guy for 3 years. Then, he found someone else. Which if Tammy really believed that a commitment-less relationship was fine... she would have just accepted that and moved on. Instead Tammy had a mental break down, and ended up on anti-depressants and 3 years of counseling.
Another girl (Linda I'll call her), was with another guy for 3 years. They joked about how they didn't need marriage or commitment. Linda even joked about marriage. Then the guy found another girl, and moved out. Linda became the most angry bitter person you ever met. She never really was the same after that.
Guy can deal with this floating relationship a ton easier than woman. They say they don't need commitment, but most of them really want something solid and secure, and while you think it's a safe perfectly fine open relationship, you are actually really harming these women. They are not designed for flings and short relationships.
oh trust me.. I wont be good with this for years. I DO want a relationship eventually. And I haven't stopped looking for one because I enjoy this guys company. Like I said, he is a great guy. But I wont pass up a date with a potential Mr. Right
