Can cohabitation be a SCAM for women that want commitment?

After reading through several questions here of marriage being a trap, now I would like to speak from the other side of women stuck in the ''we've been living together for 7 years, why isn't he proposing'' perpetual cohabitation dilemna and others advicing her to accept what she has, ignoring her wants and needs; so basically to just follow a man's agenda. It's always the same thing where she moves in with him too soon, treats him as if he were her husband, cooks and cleans for him, invest so much time, gives her youthful years and is then expecting her long-term boyfriend to propose and marry her. When that doesn't happen and he doesn't want kids either, she's left with empty proposes, worthless wasted years and her fertility years are drained. Or if she has kids with him but then wants marriage, she has a higher chance of being another single mother that couldn't get commitment from a man if a break-up happens. Then her chances in the dating pool are limited; her market value dropped. It'll then be harder for her to find another suitable man that wants marriage and accepts her with another man's child.

Personally I see it as a scam, just like men keep saying marriage is one-side... I feel exactly the same way with this cohabitation modern dating style. I'm not getting anything out of being someone's girlfriend for endless years meanwhile he's getting all the free sex, romance and maid services. It would be great if nothing was ever one-sided, if both equally benefit from each other. Moving in together isn't a step nor walking stone towards marriage, never was. The actually marriage proposal (along with a wedding date) is the step towards marriage.

By accepting cohabitation, the woman is basically accepting a long-term boyfriend that can easily dump her, not a future husband. She's not being traditional, which would be not moving in with someone that's not your fiance at least if she wants marriage. My best friend and I think it's a scam for women.

In additional, it's been already proven that living together as boyfriend and girlfriend for many years doesn't guarantee a future, happy and stable marriage. In fact, several people actually divorced shortly afterwards, since they took too much time in the dating stage.
