Oh, I meant that you seem to think that: forever boyfriend> husband from the boyfriend's/ husband's perspective. If so, why?
Well, obviously, because it gives them most of the benefits of marriage
and dating with less of the expense, risk, commitment and/or effort. Of course, my perspective may be skewed due to dating a lot of men who already went through an expensive divorce (or two.)
Also, why in your estimation is forever girlfriend a rip off compared to wife?
I'm genuinely curious about the first question. The second question I'm also curious about, but mainly because I don't see a lot of difference in a world of divorce and prenuptial agreements, but I think that maybe I am missing one of your assumptions or points?
Chapter 7 of "He's Just Not That Into You: The No-Excuses Truth to Understanding Guys" is entitled "He's Just Not That Into You If He Doesn't Want to Marry You."
Of course, Chapter 5 is entitled "He's Just Not That Into You If He's Having Sex With Someone Else", thus would seem to clearly preclude polyamory as good choice for female, but IM self-aware O the freedom and other benefits offered by polyamory is worth the loss of total devotion. MMV.
In conclusion, if you agree to "forever girlfriend" contract, you are likely with a guy who is "not that into you", yet you are giving up the options and opportunities available to you by continuing to play the open field and/or maintaining multiple partnerships. Agreeing to be somebody's "forever girlfriend" is kind of like spending all your money on an annuity from a company with only a C+ rating. I actually think it is such a rip-off contract, I would rather be the monogamous mistress of a man who is already married vs. "forever girlfriend" of a man who is monogamous with me. In fact, I think it is the prime example of women being tricked into paying too highly for monogamy vs other qualities. As in, yeah, he just sits around the apartment drinking beer and farting all weekend, but Thank the Goddess he grants access to his junk to me alone!
Also, I would advise against marriage with a pre-nup. If the dynamic going in is skewed in a manner that would make that necessary, it's not going to work well in the long run in a dyad. Possible exception here for provisions for children born previously in another relationship. Marriage is for amateurs, not professionals.
