Tell your boyfriend that it's not his problem thus it really isn't. I know it sounds horribly mean but it's the truth. He can't help that girl. If he keeps attempting to help that girl he'll end up corrupting his own life. I think he should tell this girl that he can no longer help her and then completely block her out of his life. Maybe this would give the girl the incentive to let go of her dependency and get her own damn help. I can't say if she's actually mental or not...but either way, she wants his attention obviously. Your a chick...you should know that when a girl makes such a strong effort for a guys attention...it means she wants him.

If it were me and my boyfriend couldn't handle being "mean" or telling her "no"....I sure in the hell would. If she didn't, well...we'd be scrappin. Old school style I know.

Protect what's yours. You seem to love this guy and if he loves you...after much explaining and convo on how you feel about this entire situation, then he should drop her and fully focus on his woman...you.

That's how I'd handle it personally, pertaining to my perspective and imagining if it were me and my husband. I don't know if it could work in your situation. I just recommend not taking bull junk from a girl who wants to corrupt your relationship.

Good luck hun.
