<human>: Can you give me a shortened version of the text?

I have been abandoned by people in my past, and it felt like crap.  During my darkest moments, my friend was there to help me through tough times.  Likewise, I was there for him.  However, I feel like I have to abandon a 6 year friend unfortunately, basically, he was in love with this girl, he had some legal issues, financial strains and personal  insecurities which caused a major relationship strain and his girlfriend ended up leaving him for another guy, a guy she's currently married to and has a kid with.

He's been pretty distraught about this break up for about 2 years now, and he's dated other people,  I've been literally helping him the whole time, but it seems as if he's not ever going to get over this girl for whatever reason.  To make matters even crazier, the woman's family lives literally across the street from me.

I find this inexcusable because I've given him all the advice, over a span of two years. I've taught him about acceptance, being mindful for his thoughts, and everything, yet, every time I talk to him, he's talking about how he misses his ex girlfriend.  I've hung out with him, and still sought for him to get over his ex.  2 years later.  It's like my advice doesn't get through, it's like the guy's life is just spinning around in circles.  He's doing the same exact things, it's like he listens to my advice, but he doesn't do anything with it,and goes back to his old habits.

I can suggest counseling at this point, but beyond that it seems hopeless, and honestly I just got over a girl who I was on the verge of marrying, can't be caught up with people who can't move on.  I can't be stuck reminiscing on the past because it took me 6 months to forget about my ex.  I feel like if I deal with this guy, I'll be stuck in the past thinking about my ex as well.

Your thoughts?  Sorry if my username seems hypocritical, but this is a nagging issue.
<bot>: Friend won't move on from his ex after 2 years, and it's preventing my life from progressing, wondering if I should stay in contact or just end ties.
