To reiterate, we only know what OP has shared. I’m sure there was more to it than “she wasn’t in to it.” Maybe that’s all she chose to share with OP. There are so my reasons why a woman wouldn’t want to do something like that. Judging by her age, I’m sure it played a heavy factor even if all she cared to share was what she told OP.

My point is, we shouldn’t judge anyone here in this sub too harshly. There is much more to OP’s story than he cares to share with us. I don’t think it’s a fair assumption that this woman has no consideration for his feelings just because they didn’t agree about one thing. They probably still love each other regardless. And I’m sure they will work through this together.
