Can a woman be friends with a hot guy without being romantic? Expert pinpoints warning signs

The question of whether men and women can remain "just friends" drew fresh attention when Jenny McCarthy and her husband, Donnie Wahlberg, recently bantered on her podcast about whether having an attractive male friend crosses a line. Attraction alone doesn’t necessarily threaten a friendship, according to Susan Trombetti, relationship expert and CEO of Exclusive Matchmaking in Maryland. However, unspoken feelings and growing emotional intimacy can blur boundaries, she told Fox News Digital. 5 MARRIAGE MISTAKES COUPLES MAKE WITHOUT REALIZING IT — AND HOW TO AVOID THEM "I think we can be friends with hot people … but a lot of times, I believe that friendship started with a sexual interest or romantic interest, and the timing wasn't right or the other person wasn't interested in them." Some people may maintain friendships while leaving open the possibility of a future romantic relationship, Trombetti said. "I don't think women and men can ever truly be friends," she told Fox News Digital. "I think it was always a sexual undertone that sparked the friendship and a foot-in-the-door for something more, [even if] it's 20 years from now." YOUNGER MEN ARE ATTRACTED TO OLDER WOMEN FOR REASONS THAT HAVE NOTHING TO DO WITH LOOKS Trombetti said recognizing that someone is handsome doesn’t necessarily lead to feeling chemistry with that person — and finding a friend attractive does not, on its own, constitute infidelity. The problem, she said, is when harmless awareness turns into an emotional affair. "The line between attraction with a friend and an emotional affair is a slippery slope, especially if you have a partner," the expert cautioned.

If one person develops romantic feelings that the other doesn’t share, the friendship may continue if both are single and respect clear boundaries, Trombetti said. For people already in committed partnerships, unreciprocated feelings almost always require stepping away to protect the relationship.
