One guy asks her out and she agrees and they go out and have a good time so she’s now open to a 2nd date. She likes this guy, he’s fun, but doesn’t in any way LOVE this guy. She’s just receptive to getting to know him better.
Then a 2nd guy asks her out and she goes (because she’s not in any sort of serious relationship at this point) and has a good time. She likes this other guy, too. But, again, not in LOVE nor even sure that she wants a serious relationship with this guy. He’s just fun and nice and she enjoys his company.
Is that scenario okay? These guys are not “boyfriends”, they are guys she’s dating. I’m not sure what your daughter is doing but you are the one jumping to the word “boyfriend”. Are they boyfriends (in the U.S. sense of the word)? Or is she just dating these two guys.
And what if another guy asks her out? Again, if she’s not in love with the first two guys and has made no commitments, does she not accept if she is interested in that third guy?
I would argue that this is more healthy than jumping into an exclusive relationship with ANYONE immediately.
If we assume Bigfoot exists and is intelligent, I would suggest they are more like an indigenous tribe or people like those un-contacted tribes in the Amazon rain forest or the folks on North Sentinel island.
Kind of left alone to manage and govern themselves.
