Alright, so does the way he treat you make you feel like stuff? If so, its time to cut all communication with him. In the beginning it will suck, but in the end its 100% worth it, trust me. I'll tell you a story from personal experience. It isn't about somebody online, but I'll compare your online friend to a close, real life friend.
I had a really close friend I knew for a good 2 years. We pretty much hung out every night. I helped her out of problems and was always there for her. We could always find something fun to do and were the closest friends in our group. A few months ago our friendship started falling apart due to problems within the group we hang out with. She began saying she wanted to stay away from everyone for a bit but we would still be friends, so I respected that. In the end she pretty much lost all her close friends, other then me. And because I chose to take her side, a group of my close friends stopped hanging out with me as well. I basically lost a bunch of my close friends to stick up for her.
We hung out a few times after that and talked everyday and everything seemed the same. Then about a month ago she got a boyfriend. Despite her telling me it wouldn't change our friendship, we will still hangout, etc. she began channeling me as well as everyone else out of her life. I began getting pissed my friend, who I was always there for and gave up my other friends to stick up for her, started treating me as though I didn't exist. She kept claiming we were still friends, but if I ever asked to hangout with her, she would make up some excuse. I never liked losing friends so the stuffty way she was treating me devastated me. I began just staying home, avoiding everyone, randomly flipping out on my other friends, I was just always in a generally stuffty and depressed mood.
Finally I got sick of it and accepted my friend who I used to spend the past 2 years of my life with had changed into something I wanted nothing to do with. I was upset I always heard her out, always supported her, and stuck up for her when nobody else would, even if because of that I lost all my other friends. I finally told her our friendship is over, that I did not want to hear from her anymore, that she just threw away all her good friends, and that when her boyfriend who is known for cheating on people finally cheats on her/breaks up with her, that she better not come crying to me because I'm not going to be there for her anymore.
At first, I just continued to stay away from everyone, sad that I lost my friend. But as time passed, I began accepting it. Now I get texts from other people all the time to hangout, people I know are true friends. Today, I'm pretty much completely over the whole situation. When I was friends with this girl, she would always do things to piss me off or upset me, she wouldn't do it on purpose, but it created stress regardless. Now, without her in my life, I don't have this stress anymore. From time to time I see pictures of how close me and her used to be and I feel some sadness, but it doesn't last.
In the end, the pros outweigh the cons.
