I have been talking to a guy on a dating site who ticks a lot of boxes for me. We have been chatting for about a month. Very good looking, nice and seems mature for his age. He has said he is looking for a LTR and doesn't really want a casual fling. The thing is, he is 24 and I'm 40. He is by far the youngest man to have messaged me online. I am also definitely not a cougar as I've never been with someone so much younger. WWYD? Anyone on MN had a proper relationship with a (much) YM?
