Is this friend worth contacting again or be apologised to?

Hi all

I have a male friend (A) whom i have known for 3 - 3.5 years. We used to have a common female friend (C) and i was in a brief relationship with her before we parted our ways but the friend (A) in question continued to be close friends with me (B) and this female (C). I must also mention another female (D) used to be in our group who became this guy's (A) gf and this gal became also very good friends with my ex (C) and me too became good friends with her. We were basically, all friends before our respective relationships.

After break up, we used to hangout together when sometimes in a month or more, this friend (A) returned to the city where we live. When my friend (A) used to visit us, i started to notice that he (A) started showing favoritism in terms of spending longer time with my ex (C) than before and his body language also sugessted that at times. Because of girl - girl bonding, his gf (D) grew closer to my ex (C). So, i was already in a weak position in the group, i guess. I always believed this wouldn't affect my bonding with the guy (A). But,at times, his favoritism towards my ex (C) in dinner fixtures and meetings started to prove me wrong.

One day, i wrote a angry mail to my friend (A), to which i admitted i regretted but i mentioned the points of concern but he got angry after couple of mails between us. I became also angry because at my back, he (A) asked my flatmate by calling him if i said to him anything about him(A) as A knew my flatmate pretty well. Furthermore, he also wrote very hard words. Despite this, i tried once or twice to contact him but in vain. Also, his gf (D) stopped contacting me.

Thereafter, i felt that such a friend (A) doesn't need to be contacted, so i am not in touch with him since 3 months, niether is he. I did send very brief greeting new year and b'day, to which he didn't reply.
I am a bit confused, does this guy, a close friend, i had known for some years deserve to be contacted? I also know during that time i was a bit insecure, but this repeated favoritism made me to write him angry words as he was a close friend. They were over the top but i did express genuine points.

Also, the guy has a ego i don't know among any other friends.

Thanks

The decision is yours and yours only.

Those are time killers, not friends. They are either available or unavailable. Right now they are unavailable and not worth the hassle.
I wanted a PSP with a Final fantasy logo on it, but it was unavailable to me so I stopped hassling over it.
