Search Results: getting her to see me as more than a friend

Last year my father and I beat my sister's abusive ex boyfriend. It was confirmed by mutual friends and the guy's own mother that he was abusing her. She once showed up with bruises on her arm and blamed it on the gym. Another time she was seen crying and wouldn't tell us what's going on.

I have to admit that he was almost even in the fight with my father... dad was getting him a bit more but he wasn't going down easily until I made that happen. I joined in by having a good angle and delivering a kick from behind. Fight ended right there. While my father isn't the type to further hit someone that's on the ground (unable to get up after what I did), as a finishing I proceeded to spitting in his face and placing my pet spider (a tarantula, what he hates the most) over him.

Good news is my sister was going to break up but it was so hard for her. She did already but she's thinks what I did was more disgusting and worse than what my father did to him. What? I think that POS deserved it all. Is it ever right to take revenge (physically) against an abuser?

Is there ever a time where it's too LATE to say "I love you"? It's been going on almost a year and a half--and he keeps claiming he only sees me "as a toy" (but his actions speak louder than words)! He also asked if I had feelings for him; which I SAID I liked him a lot. Since then, he's acted a lot "nicer" and more worried about it ending etc. I'm scared that my friends with benefits/casual boyfriend can't truly love someone because he witnessed a divorce... and each parent remarrying, as well as his brother getting married (who now avoids him).

His past girlfriends have been short-lived, cheated on him OR acted like they really didn't want sex with him anymore! He's also kinda has a BAD reputation; so it's really hard for him to hold on to a girl for more than a few months... but with me--it's standing the test of time. He only seems to know how to use people. Now, if anything we're "using each other" or so it looks like that from HIS point of view. To my family, it looks like he's my actual boyfriend etc.

In reality, I'm in love with him. I feel like telling him I loved him will scare him off. That being said--I feel like he needs to know someone cares about him. It's kinda like a service in which we have sex with each other and it makes us happy... BUT I have similar interests with him... I don't know what to do. I'm NOT going to end this because it's still pretty fulfilling for me :) ! Neither of us really want marriage--EITHER. So, has it gone on too long to tell him how much I really love him?
