No? On the post, OP cites how she's 10 years younger than him, making her 12. That's a huge age gap in that phase of life. Op should just tell her straight away that he doesn't want to lead her on and that they shouldn't be going out for now, obviously saying it in a way not to hurt her feelings (which she may not have, but better be safe than sorry especially due to her taking antidepressants)
Op, if you need some other help don't worry to ask
Oh, my bad, thx for the correction. Though the problem remains if OP feels anxious about the situation
