<human>: Could you distill the essence of the text into 1-3 sentences?

My best friend has always had trouble with relationships. He's afraid to trust people because he's had a string of bad relationships that were always short.

His current girlfriend of 3 months is an attention sucking type person. If the story you're telling isn't about her she'll 1-up you by making something up if she doesn't readily have something available. She's toxic.

He thinks what he feels is love, but it's nothing more than lust for a woman's touch. From day two he has been using the term so lightly. I don't know if he's ever had real love though.

I've known him for two years, and there was a point in which I fell for him a little bit. I was open and told him about it. We have moved past that since, and he is my best friend. I would do anything for him.

This relationship he is in with this girl is not a healthy one. She needs everything to be about her, so just about every week she has a fit and pretends to break up with him. She says stuff she knows will hurt him. I have more screenshots of her trying to hurt him than I do dirty pictures on my phone.

I don't know how to tell him, or how to safely bring it up. He's very stubborn but that's just part of it. I know that if I try to tell him how bad she is for him he will think I'm just trying to split them up for my own motives. I have never liked any of his girlfriends, but I tend to be right about them.

I'm scared because I don't want to lose him. He means so much to me. If I do tell him he will think I'm trying to take him for myself (which I am not.) If I don't tell him I will lose him because he will do something stupid when she finally destroys his emotional well being.

I care so much about him, but I don't know how to handle this situation. I'm scared for him. I scared to lose him.
<bot>: Best friend has a toxic relationship, but I'm afraid to try to help because of our history. Letting go of this person is not an option.
