My buddy Steve is just being used by a girl he cares deeply for.....you can tell by how she acts when they're together and by what she says when she's away from him.... he is a really good friend and has a history of psychiatric trouble so I need to choose my words very carefully, IF I should tell him at all. His last relationship ended several months ago when he was dumped by a lady he went with for about a year...this is the first lady (and the first age-appropriate one he's been with since then.) I hate to see him being played like this and really dont want him to get hurt by her, or my words....should I just butt out?
