Kitty - you're not doing anything to him. It's hard enough to be responsible for our actions without claiming responsibility to those of our alternate or future selves. You were never with him, you were single when you met me, and we fell in love. That is not something you should be made to feel guilty about. Him telling you - it's not about making you feel worse [ at least, he hopes it isn't because if it is he's going to lose all respect for the man. ] it's about making him feel better. [ that much he can relate to, he needed to tell kara he was in love with her, despite knowing she didn't want him to. of course, he didn't go into detail about how he felt, how her rejection made him feel, because that would have just extended the torture for both of them. but chekov isn't him. ]

You are not Reid and you are trying to take care of him and be there for him - that is more than a lot of people would be able to do. You're a good friend, not wanting to be his girlfriend shouldn't make you forget that.
