Warning for mature women dating younger guys

While many mature women find beautiful, loving relationships with younger men, there are always cases where it does not work. I think regardless of age any relationship may not work out, and one must be careful with the intentions of the other. More specifically, I want to share the advice I received from a reader for those ladies interested in or being pursued by younger guys:

"As an older woman of 40, who is always told that I look 28 at the most, by everyone, I get mostly younger guys wanting to go out with me. I worry, though, that once they find out my age, they don't want to get serious. They just want to hang out, have sex and enjoy me for what it's worth before finding someone closer to their own age. They write me off as immediately being incompatible with what they want. It is sad sometimes. I wonder Do these guys have honorable intentions towards these older women. Does a 28 year old interested in a 40 year old seriously considering her for marriage? Most younger guys just want sex with older women and older women have to be cautious before opening their hearts to these guys who just want all the benefits but none of the commitment."
