What have people to gain from lying? I do not know - is it pity?

There was this guy, the Ex of one of my best friends. I was friends with him too, didn´t talk much to him until they broke up though. But when she told him it was over we talked like nearly every day. I felt sorry for him, because I thought those two suit each other pretty well. Nya, I was wrong about that ^__^'''
At that time I didn´t know about him lying all the time.
As time passed I realized he wasn´t truthful at all, but I beard with it, because I felt sorry for him for being that way.
Soon after he started telling me he had certain feelings for me, but since I already was and still am in a relalationship I told him there will never be something going on between us. (Even if I had been single I still wouldn´t want to be with someone like him, I couldn´t tell him I would never want to be with a liar like him)
After that he got himself other girls, threating them like shit as time passed and was wondering why they left him soon after and as always was blaming his situation on others.
Everytime we talked he kept whining about how he was threated by others and got lost somehow in his self-pity.
He even faked some illnesses to be pitied even more!

Half a year later I got really mad at him for telling me so many lies, everytime we talked his stories changed. As always he said his words are no lies and got bitchy. I didn´t talk to him then for a few days, but again, I felt sorry for him and endured his whining again.

Stupid me XD'''''' *drop*

A few months ago he got himself another girl and disappeard, I haven´t heard from him for ages, but then one day he came back online and I was like "WTF o__O''' whining again?" and I was right. This time he had issues with his girl, she had started to act kinda cold towards him and he wasn´t sure what to do.
Few days later she threw him out and they broke up.

A few days later I read some of his Facebook comments and he had started to call her his bff, even though he had called her a bitch and what else for throwing him out, so I wrote a comment myself, wondering how people could change in heir opinion towards others so fast.
Woa, he got so mad at me telling me to leave him alone. We got into a fight, the biggest we ever had and luckily the last one.
He started insulting me and when he realized I couldn´t care less about these insults he started to take it out on my friends isulting them.

So, everyone, if you´re suddenly being harrassed by someone here on DevArt just because you´re my friend, it might be him, trying to drive a wedge between us. Be careful, everything coming out of his mouth are lies.


And still, I pity him for not being able to be honest to himself or others, for not knowing true love...
