Most Helpful Guy
first off I think it'd be cool if you put yourself in your supposed friends shoes... I don't think its right for you to refer to her in that manner as that is not something that you would've done to somebody that you had any semblance of respect for. as somebody who has been cheated on and grew up without a father because he cheated I find it grossly offensive and think that it is a deplorable act and you seem to just be sweeping that under the rug. (btw I don't just blame you but you're the one asking)
besides that it sounds to me like a friends with benefits thing and nothing more. the whole he cares for you thing is something a decent person would do, tell you nice things and help you when you're upset that's just natural. and as for "almost" falling asleep with you that is just again a normal thing, it's comforting.
