Actually, attraction to someone around the age of 15 would be ephebophilia, not paedopholia, but you woulldn't know that because you're a cretin.
As it is, 15 isn't really a desperate lunge into depraved sexual actrs. Yes, uit's weird to see a 35 year old and a 15 year old, but is it any more normal to see a 35 year old with a 16 year old? Random, imaginary boundaries that have been put in place for a black and white legal structure don't do very well if you consider them in-depth. It's weird, but that doesn't mean it's wrong in every case, and that goes for both combinations of sexes.
Of course, sometimes it really is wrong, and you've also got the proviso that just because she's a mother she should be treated leniently. It's a murky case in a lot of ways.
